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. Signed-off-by: Pavankumar Kondeti <pkondeti@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
