kirby: Clean some cruft from mainboard.c.
1. Kirby doesn't have a backlight enable GPIO on the AP since that's handled
entirely by the DP-to-LVDS bridge.
2. There is no tps65090 on the other side of the EC who's settings need to be
adjusted. If we need to turn on the LCD or backlight power manually, it will
have to be done in a different way.
3. The PMIC doesn't provide a 32KHz output for the audio codec.
BUG=None
TEST=Built for kirby.
BRANCH=None
