KVM: arm64: Register AArch64 system register entries with the sysreg xarray

In order to reduce the number of lookups that we have to perform
when handling a sysreg, register each AArch64 sysreg descriptor
with the global xarray. The index of the descriptor is stored
as a 10 bit field in the data word.

Subsequent patches will retrieve and use the stored index.
