This adds creation of a device tree that will be passed to OP-TEE.
Currently that device tree only contains the coreboot table per the
Linux coreboot device tree specification. This device tree is then
passed to OP-TEE so it can extract the CBMEM console information from
the coreboot table for logging purposes.

Currently when we build with 'SPD=spmd SPMD_SPM_AT_SEL2=0'
options, this causes a build failure as
'plat_spmd_handle_group0_interrupt' is called irrespective of
'SPMD_SPM_AT_SEL2' usage in 'spmd_group0_interrupt_handler_nwd'
So make 'plat_spmd_handle_group0_interrupt' dummy implementation
available just when spmd is enabled and SPMC_AT_EL3 is disabled.

Resetting the UART DM controller while there are still remaining
characters in the FIFO often results in corruption on the UART receiver
side. To avoid this the msm8916 crash console implementation tries to
wait until the TX FIFO is empty.
Unfortunately this might spin forever if the transmitter was disabled
before it has fully finished transmitting. In this case the TXEMT bit
console_uartdm_core_flush is waiting for will never get set.
There seems to be no good way to detect if the transmitter is actually
enabled via the status registers. However, the TX FIFO is fairly small
and should not take too long to get flushed, so fix this by simply
limiting the amount of iterations with a short timeout.
Move the code to console_uartdm_core_init to ensure that this always
happens before resetting the transmitter (also during initialization).

The memory-mapped generic timer on msm8916 has 7 timer frames, but
currently only one is exposed for usage in the non-secure world.
The platform port is currently only designed to be used as minimal PSCI
implementation, without secure world that could make use of the other
timer frames. Let's make all of them available to the normal world.
If needed this could still be changed later by reserving some timer
frames conditionally to a specific SPD being enabled in the build.

Normal world software is responsible to initialize CNTACR as needed.
There is no existing software for msm8916 that depends on having this
initialization in BL31 so drop it before anything starts to rely on it.

At the moment we only support FEAT_RAS to be either unconditionally
compiled in, or to be not supported at all.
Add support for runtime detection (FEAT_RAS=2), by splitting
is_armv8_2_feat_ras_present() into an ID register reading function and
a second function to report the support status. That function considers
both build time settings and runtime information (if needed), and is
used before we access RAS related registers.
Also move the context saving code from assembly to C, and use the new
is_feat_ras_supported() function to guard its execution.
Change the FVP platform default to the now supported dynamic
option (=2), so the right decision can be made by the code at runtime.

The current usage of RAS_EXTENSION in TF-A codebase is to cater for two
things in TF-A :
1. Pull in necessary framework and platform hooks for Firmware first
handling(FFH) of RAS errors.
2. Manage the FEAT_RAS extension when switching the worlds.
FFH means that all the EAs from NS are trapped in EL3 first and signaled
to NS world later after the first handling is done in firmware. There is
an alternate way of handling RAS errors viz Kernel First handling(KFH).
Tying FEAT_RAS to RAS_EXTENSION build flag was not correct as the
feature is needed for proper handling KFH in as well.
This patch breaks down the RAS_EXTENSION flag into a flag to denote the
CPU architecture `ENABLE_FEAT_RAS` which is used in context management
during world switch and another flag `RAS_FFH_SUPPORT` to pull in
required framework and platform hooks for FFH.
Proper support for KFH will be added in future patches.
BREAKING CHANGE: The previous RAS_EXTENSION is now deprecated. The
equivalent functionality can be achieved by the following
2 options:
- ENABLE_FEAT_RAS
- RAS_FFH_SUPPORT

The workarounds for these below mentioned errata are not implemented
in EL3, but the flags can be enabled/disabled at a platform level
based on arm/non-arm interconnect IP. The ABI helps assist the Kernel
in the process of mitigation for the following errata:
Cortex-A715: erratum 2701951
Neoverse V2: erratum 2719103
Cortex-A710: erratum 2701952
Cortex-X2: erratum 2701952
Neoverse N2: erratum 2728475
Neoverse V1: erratum 2701953
Cortex-A78: erratum 2712571
Cortex-A78AE: erratum 2712574
Cortex-A78C: erratum 2712575
EL3 provides an appropriate return value via errata ABI when the
kernel makes an SMC call using the EM_CPU_ERRATUM_FEATURES FID with the
appropriate erratum ID.
