I've spent quite a bit of time poking at this driver and it's used on
several Chromebooks I'm involved with. I'd like to get notified about
patches. Add myself as a reviewer. It's expected that changes will
still be landed through drm-misc as they always have been.

Though the parade bridge chip is a little bit of a black box, I'm at
least interested in hearing about changes to the driver since this
bridge chip is used on some Chromebooks that I'm involved with.

The GTT init and restore functions contain logic to populate the

Replace psb_gtt_takedown() with finalizer function that is only called
for unloading the driver. Use roll-back pattern for error handling in
psb_gtt_init() and _resume(). Also fixes a bug where vmap_addr was never
unmapped.
