Randall Spangler 39fd02c128 Check boot key combos if refresh key is held down ...

Instead of how it is now, where the boot key combinations are only
tested if it was a keyboard-controlled reset.  This is important for
testing/debugging EC software sync, which has a tendancy to blow away
your RW EC as soon as you flash a test EC and it reboots.  Now you can
hold down refresh+downarrow while flashing.

This does not affect keyboard-controlled dev switching, since that's
done in the AP after the EC boots.  It also does not add any new key
combos, just makes it possible to trigger the existing ones without a
Silego reset.
