KVM: arm64: nv: Configure HCR_EL2 for FEAT_NV2
Add the HCR_EL2 configuration for FEAT_NV2, adding the required
bits for running a guest hypervisor, and overall merging the
allowed bits provided by the guest.
This heavily replies on unavaliable features being sanitised
when the HCR_EL2 shadow register is accessed, and only a couple
of bits must be explicitly disabled.
Non-NV guests are completely unaffected by any of this.
