There is no definition of the output structure for the
GetVpRegisters hypercall. Hence, using the hypercall
is not possible when the output value has some structure
to it. Even getting a datum of a primitive type reads
as ad-hoc without that definition.
Define struct hv_output_get_vp_registers to enable using
the GetVpRegisters hypercall. Make provisions for all
supported architectures. No functional changes.
