Add support for enabling or disabling drivers for Arm cross build. Do not implement any enable/disable lists yet. Enabling drivers is useful when building for an SoC where we only want to build a few drivers. That way the list won't be too long. Similarly, disabling drivers is useful when we want to disable only a few drivers. Both of these are advantageous mainly in aarch64 -> aarch64 (or arch -> same arch) builds, where the build machine may have the required driver dependencies, yet we don't want to build drivers for a specific SoC. If enable_drivers is a non-empty list, build only those drivers, otherwise build all drivers and add them to enable_drivers. If disable_drivers is non-empty list, build all drivers specified in enable_drivers except those in disable_drivers. There are two drivers, bus/pci and bus/vdev, which break the build if not enabled. Address this by always enabling these if the user disables them or doesn't specify in their allowlist. Also remove the old Makefile arm configuration options which don't do anything in Meson.
