skylake: Properly handle apshutdown when AP is already shutdown

Browse Source 
If the AP is already shutdown, apshutdown would previously power the AP
up with a power press. Fix this by making sure we're not already in G3
before triggering the power press.

BUG=chrome-os-partner:40677
TEST=Run 'apshutdown' on glados while in G3, verify that AP does not
power up.
BRANCH=None
