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.

V4:
- Added ACKed-by details for PHY driver.
- Used BIT macro instead of (1 << index) usage as suggested by Chunfeng Yun.
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.
