These GPU drivers only depend on the RESET_CONTROLLER config
option to fix build issues that existed when there weren't stub
reset APIs for reset controller consumers. Given that these
drivers aren't providing any reset controllers themselves, they
don't actually depend on the API to build (just to function) so
they don't need to depend on it. Remove the dependency to fix
recursive build errors like the following:

drivers/usb/Kconfig:39:error: recursive dependency detected!
drivers/usb/Kconfig:39: symbol USB is selected by MOUSE_APPLETOUCH
