KVM: arm64: Unify HDFG[WR]TR_GROUP FGT identifiers

Browse Source 
There is no reason to have separate FGT group identifiers for
the debug fine grain trapping. The sole requirement is to provide
the *names* so that the SR_FGF() macro can do its magic of picking
the correct bit definition.

So let's alias HDFGWTR_GROUP and HDFGRTR_GROUP.
