fix(ras): remove RAS_FFH_SUPPORT and introduce FFH_SUPPORT

This patch removes RAS_FFH_SUPPORT macro which is the combination of
ENABLE_FEAT_RAS and HANDLE_EA_EL3_FIRST_NS. Instead introduce an
internal macro FFH_SUPPORT which gets enabled when platforms wants
to enable lower EL EA handling at EL3. The internal macro FFH_SUPPORT
will be automatically enabled if HANDLE_EA_EL3_FIRST_NS is enabled.
FFH_SUPPORT along with ENABLE_FEAT_RAS will be used in source files
to provide equivalent check which was provided by RAS_FFH_SUPPORT
earlier. In generic code we needed a macro which could abstract both
HANDLE_EA_EL3_FIRST_NS and RAS_FFH_SUPPORT macros that had limitations.
Former was tied up with NS world only while the latter was tied to RAS
feature.

This is to allow Secure/Realm world to have their own FFH macros
in future.

refactor(ras): replace RAS_EXTENSION with FEAT_RAS

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

Tegra194: ras: split up RAS error clear SMC call.

In order to make sure SMC call is within 25us, this patch reduces number of RAS
errors accessed to 8 at most for each SMC call and takes a input/output
parameter to specify in progress RAS error record index.

The measured SMC call latency is about 20us under Linux test kernel driver.

Tegra194: SiP: clear RAS corrected error records

This patch introduces a function ID to clear all the RAS error
records for corrected errors.

Per latest requirement, ARM RAS corrected errors will be reported to
lower ELs via interrupts and cleared via SMC. This patch provides
required function to clear RAS error status.

This patch also sets up all required RAS Corrected errors in order to
route RAS corrected errors to lower ELs.

Tegra194: Enable fake system suspend

Fake system suspend for Tegra194, calls the routine
tegra_secure_entrypoint() instead of calling WFI.
In essence, this is a debug mode that ensures
that the code path of kernel->ATF and back to kernel
is executed without depending on other components
involved in the system suspend path.

This is for ensuring that verification of system suspend
can be done on pre-silicon platforms without depending on
the rest of the layers being enabled.
