baytrail: gfx: Don't configure hotplug + backlight registers
- The hotplug register doesn't work in the way we describe. Just leave
it at default.
- The backlight registers will be configured by the OS driver.
BUG=chrome-os-partner:27304
TEST=Manual on Rambi. Boot system in both dev and normal mode, verify
that display comes up. Also verify that display functions after warm
reboot and suspend / resume.
BRANCH=rambi+squawks
