There are several bits of Hyper-V-related code that today live in
arch/x86 but are not really specific to x86_64 and will work on arm64
too.
Some of these will be needed in the upcoming mshv driver code (for
Linux as root partition on Hyper-V). So this is a good time to move
them to drivers/hv.

Changes in v3:
* Just use percpu input page for the hypercall [Michael Kelley]
* Move the calls to hv_get_partition_id() back to arch code [Michael Kelley]
* Rename struct hv_get_partition_id to hv_output_get_partition_id
[Michael Kelley]
Changes in v2:
* Fix dependence on percpu output page by using a stack variable for the
hypercall output [Michael Kelley]
* Remove unnecessary WARN()s [Michael Kelley]
* Define hv_current_partition_id in hv_common.c [Michael Kelley]
* Move entire hv_proc.c to drivers/hv [Michael Kelley]
