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.
