drivers: stm32_i2c: use compatible st,stm32mp15-i2c-non-secure

Change STM32 I2C driver to rely on the compatible DT property of the
node to store whether the bus is expected assigned to secure or
non-secure world. Using a non-secure I2C bus in OP-TEE on stm32mp1
platforms is something expected only on STM32MP15 variant for
compatibility with platform already supported in upstream Linux/U-Boot
components, as defined by st,stm32mp15-i2c-non-secure specific
compatible string ID.

drivers: counter: stm32_stgen: add STGEN driver

STGEN is the platform timer. It generates a time-count value that provides
a consistent view of time for multiple processors and other blocks in a
device. It is physically linked to the ARM generic timer.

Add the STGEN driver that is in charge of configuring the ARM generic
timer source and send an SMC to the BL31 monitor to update the CP15
register. This driver is only compatible for 64bits platforms.

core: boot_mem: keep track of padding

When boot_mem_alloc() allocates memory up to alignment - 1 number of
bytes may have be skipped to satisfy the required alignment of the
returned pointer. If the skipped bytes, or padding, is large enough,
it's recorded in a list of padding. The list of paddings can be
processed and consumed with boot_mem_foreach_padding(). This allows
sufficiently large paddings to be added to for instance the heap instead
of being wasted.

All read/write secure memory is covered by MEM_AREA_SEC_RAM_OVERALL,
sometimes using an aliased map. But secure read-only or execute core
memory is not covered as that would defeat the purpose of
CFG_CORE_RWDATA_NOEXEC.

Since the partition TA memory isn't accessed via MEM_AREA_TA_RAM any
longer, don't map it using the partition specific map.

This is needed later where unification of OP-TEE core and physical TA

Add VCORE_FREE_{PA,SZ,END_PA} defines to identify the unused and free
memory range at the end of TEE_RAM_START..(TEE_RAM_START +
TEE_RAM_VA_SIZE).

VCORE_FREE_SZ is 0 in a pager configuration since all the memory is
used by the pager.

The VCORE_FREE range is excluded from the TEE_RAM_RW area for
CFG_NS_VIRTUALIZATION=y and instead put in a separate NEX_RAM_RW area.
This makes each partition use a bit less memory and leaves the
VCORE_FREE range available for the Nexus.

The VCORE_FREE range is added to the TEE_RAM_RW area for the normal
configuration with CFG_NS_VIRTUALIZATION=n and CFG_WITH_PAGER=n. It's in
practice unchanged behaviour in this configuration.
