To save the power consumption, add a new compatible to support forcibly
suspend the USB PORTA/B/C via OHCI Interrupt Configuration SFR Register.

Changes in v3:
 - Change the compatible description for more precise.

Changes in v2:
 - Add compatible to support forcibly suspend the ports.
 - Add soc/at91/at91_sfr.h to accommodate the defines.
 - Add error checking for .sfr_regmap.
 - Remove unnecessary regmap_read() statement.
 - Use the new compatible for ohci-node.
