mb/google/skyrim: Disable L1.2 for SD port
Having L1.2 enabled on the SD port increases the kernel resume times by
between 30 & 40ms. This patch disables L1.2 on SD to get that time
back.
As with needing to have hotplug enabled on the SD card, this seems like
a driver issue, so hopefully that will get sorted out and this patch
can be reverted.
BUG=b:274025743
TEST=resume times are decreased.
BRANCH=skyrim
