This patch series adds OTG support on XUSB hardware used in Tegra210 and
Tegra186 SoCs.

This patchset is composed with :
 - dt bindings of XUSB Pad Controller
 - dt bindings for XUSB device Driver
 - Tegra PHY driver for usb-role-switch and usb-phy
 - Tegra XUSB host mode driver to support OTG mode
 - Tegra XUSB device mode driver to use usb-phy and multi device mode
 - dts for XUSB pad controller
 - dts for xudc

Tegra Pad controller driver register for role switch updates for
OTG/peripheral capable USB ports and adds usb-phy for that corresponding
USB ports.

Host and Device mode drivers gets usb-phy from USB2's phy and registers
notifier for role changes to perform corresponding role tasks.

Tests done:
 - device mode support using micro-B USB cable connection between ubuntu
   host and DUT on micro-B port
 - host mode support by connecting pen-drive to micro USB port on DUT
   using micro-B OTG cable.
 - toggling between these 2 modes by hot plugging corresponding cables.

DUT: Jetson-tx1, Jetson tx2.
