From: Hebbar Gururaja <gururaja.hebbar@ti.com>
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.

Mugunthan V N
Add pinmux configurations for MII based CPSW ethernet to am335x-bone.
In this patch, only single named mode/state is added and these pins
are configured during pinctrl driver initialization.
Default mode is nothing but the values required for the module during
active state. With this configurations module is functional as
expected.
Todo:
- if an idle state is available for pins, add support for it.
