Conditional flag enables are strongly discouraged in TF-A because they
cause cyclic dependencies that we are not equipped to deal with. On a
real platform, ARM_ARCH_{MAJOR, MINOR} should be set in platform.mk but
WORKAROUND_CVE_2025_0647 gets its value before platform.mk is evaluated.
Further, WORKAROUND_CVE_2025_0647 is only present on cores the feature
set of which is known ahead of time. Using ARM_ARCH_{MAJOR, MINOR} is
redundant and incorrect (as it sidesteps the feature detection
mechanism).
This patch solves both of these issues by making
WORKAROUND_CVE_2025_0647 unconstrained by ARM_ARCH_{MAJOR, MINOR} and
making it buildable on a v8.0 target. Running the workaround will only
happen on affected cores which, by definition, all implement armv8.5 so
doing any checks in unnecessary.
