feat(rdaspen): event handler for CPU RAS

This patch introduces assembly helpers for cleaning CPU
RAS, and introduces a way to deassert FAULT IRQ generated
from CE injection.

This also enables all inband errors to be handled on AP according
to a CPU RAS event handler:

- Skips spurious entries – returns early when
`ERXSTATUS.{V|CE}` is already clear, disposing of queued phantom
interrupts.

- Clears the error record – rewrites `ERXSTATUS_EL1`, zeros
`ERXMISC0`, `PFG_CTL`, and `PFG_CDN`, then logs the post clear state
for firmware trace.

Inband errors only consist of:
- Corrected Errors
- Deferred Errors

- Change the RAS CPU intr handler logs from VERBOSE to WARN.

feat(rdaspen/ras): intr RAS handling for PC CPU

This introduces and enables the RAS framework and enables
the RAS for CPU handling.

This commit ensures that RAS settings are initialized on
all CPU cores during the firmware boot stage. Previously,
the initialization for RAS processing was only done on
the primary CPU core.

This also introduces a custom bl31_platform_setup to
allow RAS specific intialisations.
