[v9,11/14] build: disable Arm drivers

  A few options that disabled drivers in the old makefiles were improperly
ported to the meson build system. Fix this by adding a to the list of
disabled drivers, similarly how the command line option works. Remove
unneeded driver options ported from the old makefile system.
Add support for removing drivers for cross builds.
