fix(measured-boot): fix verbosity level of RSS digests traces

Most traces displayed by log_measurement() use the INFO verbosity
level. Only the digests are unconditionally printed, regardless of
the verbosity level. As a result, when the verbosity level is set
lower than INFO (typically in release mode), only the digests are
printed, which look weird and out of context.

fix(errata): workaround for Neoverse-V1 erratum 2294912

Neoverse-V1 erratum 2294912 is a cat B erratum that applies to revisions
r0p0 - r1p1 and is still open. The workaround is to set bit[0] of
CPUACTLR2_EL1 to force PLDW/PFRM ST to behave like PLD/PRFM LD and not
cause invalidations to other PE caches.

refactor(context mgmt): refactor EL2 context save and restore functions

This patch splits the el2_sysregs_context_save/restore functions
into multiple functions based on features. This will allow us to
selectively save and restore EL2 context registers based on
features enabled for a particular configuration.

For now feature build flags are used to decide which registers
to save and restore. The long term plan is to dynamically check
for features that are enabled and then save/restore registers
accordingly. Splitting el2_sysregs_context_save/restore functions
into smaller assembly functions makes that task easier. For more
information please take a look at:

feat(trbe): add trbe under feature detection mechanism

This change adds "FEAT_TRBE" to be part of feature detection mechanism.

Previously feature enablement flags were of boolean type, containing
either 0 or 1. With the introduction of feature detection procedure
we now support three states for feature enablement build flags(0 to 2).

Accordingly, "ENABLE_TRBE_FOR_NS" flag is now modified from boolean
to numeric type to align with the feature detection.

The workaround sets IMP_CLUSTERACTLR_EL1[16:15] bits to 0b11 to disable
clock gating of the SCLK domain. This will increase the idle power
consumption.
