arm64: KVM: VHE: Make __fpsimd_enabled VHE aware
As non-VHE and VHE have different ways to express the trapping of FPSIMD registers to EL2, make __fpsimd_enabled a patchable predicate and provide a VHE implementation. Reviewed-by: Christoffer Dall <christoffer.dall@linaro.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
