Subject: [PATCH v3 7/9] ARM: tegra: Add Tegra124 XUSB mailbox and xHCI controller

Add nodes for the Tegra XUSB mailbox and Tegra xHCI controller and
add the PHY mailbox channel to the XUSB padctl node.

Signed-off-by: Andrew Bresticker <abrestic@...omium.org>
---
Changes from v2:
 - Dropped channel specifier from mailbox bindings.
 - Added mbox-names properties.
Changes from v1:
 - Updated to use common mailbox bindings.
 - Added remaining clocks/resets.
