From: Kalliguddi, Hema <[email protected]>

Introduced the suspend/resume function for the OMAP4430 internal PHY.
This will be used by the twl6030-usb transceiver driver.
Moved the clock enable/disable function calls and power on/off of the PHY
code from power on/off functions to suspend/resume function.
