usb: Add Intel Langwell USB OTG Transceiver Driver
This adds support for the USB transceiver driver in the Langwell chipset used on the Intel MID platforms. It folds up the original patch set which includes basic support for the device, PHY low power mode (Please notice that there is a limitation, after we drive VBus down, 2ms delay is required from SCU FW to sync up OTGSC register with USBCFG register), software timers (the hardware timers do not work in low power mode), HNP, SRP.
