Amend cpsw controller to optionally take a pin control handle and set
the state of the pins to:
- "default" on boot, resume
- "sleep" on suspend()
This should make it possible to optimize energy usage for the pins
for the suspend/resume cycle.
If any of the above pin states are missing in dt, a warning message
about the missing state is displayed.
If certain pin-states are not available, to remove this warning message
pass respective state name with null phandler.

This still needs some work:
+ /*
+ * Since we continue even when pinctrl node is not found,
+ * Invalidate pins as not available. This is to make sure that
+ * IS_ERR(pins_xxx) results in failure when used.
+ */
The second, third, fourth, and fifth lines are not tabbed correctly. They
should all be two TABs and a SPACE.
Secondly, comments in the networking are to be formatted:
/* Like
* this.
*/
Will fix this and will resubmit the next version today.
