At the moment we only support for FEAT_RNG to be either unconditionally
compiled in, or to be not supported at all.
Add support for runtime detection (FEAT_RNG=2), by splitting
is_armv8_5_rng_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 the RNDRRS system register.
Change the QEMU platform default to the now supported dynamic option (=2),
so the right decision can be made by the code at runtime.
