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 Change-Id: I88cdc41ce8bb96a6b17aeb7f24b1c5619471b24e Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 6c966edfa29df1049c469442dc3ad8bf8b4197b1 Original-Change-Id: I3d98203185f52ed751a5d3045a0ee8f9b4dfbc71 Original-Signed-off-by: David Hendricks <dhendrix@chromium.org> Original-Signed-off-by: huang lin <hl@rock-chips.com> Original-Reviewed-on: https://chromium-review.googlesource.com/274876 Reviewed-on: http://review.coreboot.org/10630 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marc.jones@se-eng.com>
