usb: fixes for v3.13-rc4 

DWC3 learned that it can't resume a PHY which wasn't
 initialized and it also learned to not leave PHY powered
 up in case of an error.
 
 twl6030-usb PHY driver got a fix for a signedness bug in
 twl6030_readb().
 
 Tegra PHY driver got a bug fix where it could return success
 even though there was an error.
