plat-ti: Fix initialisation order
Since commit 358cdcd2b079 ("core: arm32: initialize secure monitor late") TI platforms have been broken due to only initialising the HUK in `init_sec_mon` after the SSK has been derived/generated from it in the `tee_fs_init_key_manager` service init.
Move initialisation of HUK into an `early_init` registration to restore the correct order of operations.
Secure monitor initialisation cannot be moved into the `early_init()` as the secure monitor stack is not yet initialised.

Since there are some cross-platform console drivers, we let console_init() be common code to have a chance to initialize those console drivers (e.g., semihosting console).
If the cross-platform console drivers are not configured to be compiled, plat_console_init() will be invoked to initialize platform-specific console driver.

core: define main interrupt controller data from its driver
All but one platforms define CPU core interrupt controller from their platform main.c source file next to its main interrupt handler. This change factorize these implementation by moving the definition of the controller data instance straight in the controller driver source file. This change makes each controller driver to implement straight itr_core_handler() function, preventing a extra branch on interrupt execution. Interrupt controller driver initialization function now straight calls itr_core_init().
This changes treats case when CFG_CORE_WORKAROUND_ARM_NMFI is enable to not conflict with core/arch/arm/kernel/thread.c that already overrides itr_core_handler() weak implementation.
With this change, the main controller initialization function (gic_init(), gic_init_base_addr(), gic_cpu_init() and hfic_init()) no more gets the controller data as input argument.
As a consequence, definition of struct hfic_data and struct gic_data moves from their respective driver header file to the respective driver source file.
As a consequence, gic_dump() no more requires an argument.

plat: arm: refactor GIC initialization
All platforms (except STM32MP1) follow the same pattern during GIC initialization: get virtual addresses for distributor (and optionally, for CPU interface), check that they are not NULL, call either gic_init() or gic_init_base_addr().
We can move most of this logic into gic_init_base_addr(), while platform-specific code will supply only base physical addresses for distributor and CPU interface. This will simplify and align platform code.
ST32MP1 had more complex logic, as it used io_pa_or_va_secure() to get MMIO range addresses. However, as main_init_gic() called assert(cpu_mmu_enabled()), there is no sense in using io_pa_or_va_secure(), because we already ensured that VA will be always used. Thus assert() call was moved to gic_init_base_addr(), and STM32MP1 were aligned with other platforms.

core_mmu: fix phys_to_virt() to check length
phys_to_virt() function without length parameter doesn`t always have ability to find the correct mapping for requested physical address. This is because physical address can be mapped in the same time in different virtual regions with different length. So the first found region which contains the requested physical address possibly doesn`t have enough mapped data. This is fixed by adding the length parameter to phys_to_virt() function. Length parameter can be set to 1 if caller knows that requested (pa + len) doesn`t cross mapping granule boundary.
core_mmu_get_va() and io_pa_or_va() functions now are take length parameter too as they based on phys_to_virt() in case of MMU enabled.

core_mmu: do not restrict device memory mapping to PGDIR_SIZE granularity
Device memory registered via register_phys_mem() is currently rounded up/down to CORE_MMU_PGDIR_SIZE (1 MiB, or 2 MiB for LPAE). This is not needed and possibly incorrect for SoCs that define I/O memory maps with regions aligned on a small page (4 KiB), because using a larger granularity could result in overlaps between secure and non-secure mappings. This could cause issues depending on the type of memory firewall used by the SoC and its configuration. In any case, memory types other than MEM_AREA_IO_{SEC,NSEC} *can* be mapped with small page granularity using register_phys_mem(), so the situation is a bit inconsistent.
This commit removes the rounding by default and provides a new macro: register_phys_mem_pgdir(). Platforms that still need to use PGDIR_SIZE granularity (typically because it consumes less page table space) need to replace register_phys_mem() by register_phys_mem_pgdir().
In order to avoid any functional change in platform code, all calls to register_phys_mem() with device memory are replaced with register_phys_mem_pgdir(). In addition, CORE_MMU_DEVICE_SIZE is removed and replaced with CORE_MMU_PGDIR_SIZE since there is no unique mapping size for device memory anymore.

core: remove __early_bss
Initialize the .bss section early from assembler before entering C code. As a result, the __early_bss qualifier is not needed anymore. Remove it, as well as the related symbols (__early_bss_start and __early_bss_end).
This makes the code simpler hence easier to maintain, at the expense of initialization time, since .bss is cleared before CPU caches are turned on (and doing it later would mean some C function have been called already). Here are some performance numbers measured on HiKey. The "memset" column measures the time it takes to clear .bss in C, without this patch. The "assembly" column reports the time taken by the clear_bss loop in this patch. Timings were performed using CNTPCT. Worst case is a ~1 ms overhead in boot time.
