arm64: kvm: Add comments around __kvm_nvhe_ symbol aliases

This patch is part of a series which builds KVM's non-VHE hyp code separately
from VHE and the rest of the kernel.

With all source files split between VHE/nVHE, add comments around the list of
symbols where nVHE code still links against kernel proper. Split them into
groups and explain how each group is currently used.

Some of these dependencies will be removed in the future.
