The only way to truly clean up intel_display.[ch] is to move stuff out
of them until there's absolutely nothing left.
Start moving the high level display driver entry points, i.e. functions
called from top level driver code only, to a new file, which we'll call
intel_display_driver.c. The intention is that there's no low-level
display code or details here. This is an in-between layer.
Initially, move intel_display_driver_register() and
intel_display_driver_unregister() there.
