Create sub-menus for bus drivers and remove artificial dependencies
between vfio-pci and vfio-platform and other variant drivers like
vfio-amba, mlx5-vfio-pci, or hisi-acc-vfio-pci.

This is an alternative proposal vs [1], which attempts to make the
vfio-pci-core module individually selectable, even without built
dependencies, in order to avoid the select per variant module.

The solution presented here is my preference, I don't see the select as
overly burdensome or error prone, we have very good randconfig test
coverage, and I prefer to not allow building module which have no
in-kernel requirements.  Thanks,

Alex

v3: Move the depends line up to the menu level for fsl Kconfig as
    discussed with Cedric in v2.  Add R-bs.

v2: Move dependencies from config VFIO_PLATFORM to menu, make existing
    platform reset drivers depend on VFIO_PLATFORM.  Add R-bs.
