vfio/platform: Cleanup Kconfig
Like vfio-pci, there's also a base module here where vfio-amba depends on
vfio-platform, when really it only needs vfio-platform-base. Create a
sub-menu for platform drivers and a nested menu for reset drivers. Cleanup
Makefile to make use of new CONFIG_VFIO_PLATFORM_BASE for building the
shared modules and traversing reset modules.
