At present, drivers/Makefile will subst =m to =y for CONFIG_HYPERV for hv
subdir. Also, drivers/hv/Makefile replaces =m to =y to build in
hv_common.c that is needed for the drivers. Moreover, vmbus driver is
built if CONFIG_HYPER is set, either loadable or builtin.

This is not a good approach. CONFIG_HYPERV is really an umbrella config that
encompasses builtin code and various other things and not a dedicated config
option for VMBUS. Vmbus should really have a config option just like
CONFIG_HYPERV_BALLOON etc. This small series introduces CONFIG_HYPERV_VMBUS
to build VMBUS driver and make that distinction explicit. With that
CONFIG_HYPERV could be changed to bool.

For now, hv_common.c is left as is to reduce conflicts for upcoming patches,
but once merges are mostly done, that and some others should be moved to
virt/hyperv directory.
