veyron_mickey: Apply differences between Brain and Mickey

Mickey:
- Does not have power key
- Does not have an audio codec(all audio goes thru HDMI)
- VCC18_LCD moved to VLDO8 and needs to be turned on (was
  connected to VSWOUT2 earlier)

(write32() --> writel() for cherry-pick)

BUG=none
BRANCH=none
TEST=Boot from mickey board, and hdmi work normal
