hyperv: Move hv_current_partition_id to arch-generic code
Move hv_current_partition_id and hv_get_partition_id() to hv_common.c,
and call hv_get_partition_id() on arm64 in hyperv_init(). These aren't
specific to x86_64 and will be needed by common code.
Set hv_current_partition_id to HV_PARTITION_ID_SELF by default.
Rename struct hv_get_partition_id to hv_output_get_partition_id, to
make it distinct from the function hv_get_partition_id(), and match
the original Hyper-V struct name.
Remove the BUG()s. Failing to get the id need not crash the machine.
