This modifies the CPU interface to more accurately match an AArch64-supporting CPU as opposed to an ARM11 one. Two of the methods don't even make sense to keep around for this interface, as Adv Simd is used, rather than the VFP in the primary execution state. This is essentially a modernization change that should have occurred from the get-go.
