The cs cannot change back to 'high' when the count is

These patches clean up some things I noticed while fixing suspend/resume
behavior. The first four are minor code improvements. The last one adds
a shutdown hook to minimize power consumption on boards without a PMIC.
Now that the fixes series is merged, I'm resending this series rebased
on top of
The Ethernet MAC and PHY are usually major consumers of power on boards
which may not be able to fully power off (those with no PMIC). Powering
down the MAC and internal PHY saves power while these boards are "off".
