KVM: arm64: Drop the CPU_FTR_REG_HYP_COPY infrastructure

Browse source

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.
