mb/google/zork: Remove code that reconfigured the backlight GPIO
The SMU code was assuming that GPIO 85 was used for a fan, which caused
interesting backlight flickering. That has now been fixed, so remove
the code that reconfigured it to a GPIO on resume.
BUG=b:155667589
TEST=Verify the screen does not flicker on resume from S3
BRANCH=Zork
