Subject: [PATCH v2 3/4] ARM: tegra: tegra124: Add XUSB pad controller

From: Thierry Reding <treding@...dia.com>

The device tree node in the SoC file contains only the resources (such
as registers, resets, ...) but none of the lane assignment information
since that's board specific and belongs in the board file.

Signed-off-by: Thierry Reding <treding@...dia.com>
---
Changes in v2:
- include dt-bindings/pinctrl/pinctrl-tegra-xusb.h so that board files
  don't have to include it explicitly
- remove unneeded #address-cells/#size-cells = <0>
- add padctl label for XUSB pad controller node
