KVM: arm64: Expose ID_AA64FPFR0_EL1 as a writable ID reg

Browse source

ID_AA64FPFR0_EL1 contains all sort of bits that contain a description
of which FP8 subfeatures are implemented.

We don't really care about them, so let's just expose that register
and allow userspace to disable subfeatures at will.
