ti: k3: common: Add platform core management helpers

The K3 family of SoCs has multiple interconnects. The key interconnect
for high performance processors is the MSMC3 interconnect. This is
an io-coherent interconnect which exports multiple ports for each
processor cluster.

Sometimes, port 0 of the MSMC may not have an ARM cluster OR is isolated
such that the instance of ATF does not manage it. Define macros
in platform_def.h to help handle this.

ti: k3: Setup initial files for platform

Create the baseline Makefile, platform definitions file and platform
specific assembly macros file. This includes first set of constants
for the platform including cache sizes and linker format and a stub for
BL31 and the basic memory layout

K3 SoC family of processors do not use require a BL1 or BL2 binary,
since such functions are provided by an system controller on the SoC.
This lowers the burden of ATF to purely managing the local ARM cores
themselves.

plat/arm: Migrate AArch64 port to the multi console driver

The old API is deprecated and will eventually be removed.

Arm platforms now use the multi console driver for boot and runtime
consoles. However, the crash console uses the direct console API because
it doesn't need any memory access to work. This makes it more robust
during crashes.

The AArch32 port of the Trusted Firmware doesn't support this new API
yet, so it is only enabled in AArch64 builds. Because of this, the
common code must maintain compatibility with both systems. SP_MIN
doesn't have to be updated because it's only used in AArch32 builds.
The TSP is only used in AArch64, so it only needs to support the new
API without keeping support for the old one.

Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
causes the UARTs to reset (except for the one used by the TSP). This
means that they must be unregistered when suspending and re-registered
when resuming. This wasn't a problem with the old driver because it just
restarted the UART, and there were no problems associated with
registering and unregistering consoles.

The size reserved for BL2 has been increased.

Panic in BL1 when TB_FW_CONFIG is invalid

In Arm platforms, when using dynamic configuration, the necessary
parameters are made available as a DTB. The DTB is loaded by BL1 and,
later on, is parsed by BL1, BL2 or even both, depending on when
information from the DTB is needed.

When the DTB is going to be parsed, it must be validated first, to
ensure that it is properly structured. If an invalid DTB is detected
then:
- BL1 prints a diagnostic but allows execution to continue,
- BL2 prints a diagnostic and panics.

Now the behaviour of BL1 is changed so for it also to panic. Thus, the
behaviour of BL1 and BL2 is now similar.

Keep in mind that if BL1 only loads the DTB but it doesn't need to
read/write it, then it doesn't validate it. The validation is done only
when the DTB is actually going to be accessed.

allwinner: Add security setup

Some peripherals are TrustZone aware, so they need to be configured to
be accessible from non-secure world, as we don't need any of them being
exclusive to the secure world.
This affects some clocks, DMA channels and the Secure Peripheral
Controller (SPC). The latter controls access to most devices, but is not
active unless booting with the secure boot fuse burnt.

allwinner: Add functions to control CPU power/reset

sun50i_cpu_on will be used by the PSCI implementation to initialize
secondary cores for SMP. Unfortunately, sun50i_cpu_off is not usable by
PSCI directly, because it is not possible for a CPU to use this function
to power itself down. Power cannot be shut off until the outputs are
clamped, and MMIO does not work once the outputs are clamped.

But at least CPU0 can shutdown the other cores early in the BL31 boot
process and before shutting down the system.

allwinner: Introduce basic platform support

This platform supports Allwinner's SoCs with ARMv8 cores. So far they
all sport a single cluster of Cortex-A53 cores.

"sunxi" is the original code name used for this platform, and since it
appears in the Linux kernel and in U-Boot as well, we use it here as a
short file name prefix and for identifiers.

This port includes BL31 support only. U-Boot's SPL takes the role of the
primary loader, also doing the DRAM initialization. It then loads the
rest of the firmware, namely ATF and U-Boot (BL33), then hands execution
over to ATF.

This commit includes the basic platform code shared across all SoCs.
There is no platform.mk yet.
