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

This patchset is composed with :
 - dt bindings of XUSB Pad Controller
 - Tegra XUSB device mode driver to add vbus_draw support 
 - Tegra PHY driver for charger detect support

Tests done:
 - Connect USB cable from ubuntu host to micro-B port of DUT to detect
   SDP_TYPE charger
 - Connect USB cable from external powered USB hub(which inturn connects
   to ubuntu host) to micro-B port of DUT to detect CDP_TYPE charger.
 - Connect USB cable from USB charger to micro-B port of DUT to detect
   DCP_TYPE charger.
DUT: Jetson-tx1, Jetson tx2.

V3:
 - Added ACKed-by details for PHY driver and DT changes.
 - Functions and its arguments are aligned.
 - Tabs are used for alignment of MACRO's
 - For vbus_draw USDC callback, usb_phy set_power error is propogated.
 - Fixed various comments given by thierry.
V2:
 - Added ACKed-by details for DT patches.
 - All patches rebased.
