KVM: arm64: nv: Add support for FEAT_ATS1A
Handling FEAT_ATS1A (which provides the AT S1E{1,2}A instructions)
is pretty easy, as it is just the usual AT without the permission
check.
This basically amounts to plumbing the instructions in the various
dispatch tables, and handling FEAT_ATS1A being disabled in the
ID registers.
