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.
