[PATCH v2 3/3] KVM: arm64: Drop the CPU_FTR_REG_HYP_COPY infrastructure

Now that the read_ctr macro has been specialised for nVHE, the whole CPU_FTR_REG_HYP_COPY infrastrcture looks completely overengineered. Simplify it by populating the two u64 quantities (MMFR0 and 1) that the hypervisor need. Signed-off-by: Marc Zyngier --- arch/arm64/include/asm/cpufeature.h
