feat(cpufeat): initialize HFG*_EL2 registers

HFG*_EL2 registers control the fine-grained traps introduced by
FEAT_FGT. These traps come enabled by default so old systems unaware
of this feature can be trapped to EL3, not being able to handle the
trap correctly. This patch disables all fine-grained traps by default
to prevent such unexpected behavior.
