KVM: arm64: Use the xarray as the primary sysreg/sysinsn walker

Browse source

Since we always start sysreg/sysinsn handling by searching the
xarray, use it as the source of the index in the correct sys_reg_desc
array.

This allows some cleanup, such as moving the handling of unknown
sysregs in a single location.
