usb: phy: patches for v3.6 merge window

Browse source 
We are starting to support multiple USB phys as
 we should thanks for Kishon's work. DeviceTree support
 for USB PHYs won't come until discussion with DeviceTree
 maintainer is finished.
 
 Together with that series, we have one fix for twl4030
 which missed a IRQF_ONESHOT annotation when requesting
 a threaded IRQ without a top half handler, and removal
 of an unused variable compilation warning to isp1301_omap.
