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)

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