drivers/virt: Drop VIRT_DRIVERS build dependency

All of the objects in drivers/virt/ have their own configuration symbols to
gate compilation. I.e. nothing gets added to the kernel with
CONFIG_VIRT_DRIVERS=y in isolation.

Unconditionally descend into drivers/virt/ so that consumers do not need to
add an additional CONFIG_VIRT_DRIVERS dependency.

Fix warnings of the form:

    Kconfig warnings: (for reference only)
       WARNING: unmet direct dependencies detected for TSM
       Depends on [n]: VIRT_DRIVERS [=n]
       Selected by [y]:
       - PCI_TSM [=y] && PCI [=y]

...where PCI_TSM selects CONFIG_TSM, but fails to select
CONFIG_VIRT_DRIVERS.
