Pavankumar Kondeti 5155e2c70f MSM: Add USB support for MSM7x30
Add USB OTG, peripheral and host devices.  This patch also adds
usb_phy_clk which is required for resetting the PHY.  VBUS power up
and shutdown routines depends on PMIC module.  As PMIC driver is
unavailable, configure USB in peripheral only mode.
