Subject: [PATCH v4 2/2] arm: omap5: dts: add palmas-usb node

From: Felipe Balbi <balbi@...com>

Without this node, there will be no palmas
driver to notify dwc3 that a cable has
been connected and, without that, dwc3
will never initialize.

[ kishon@...com : fix vbus-supply value after SMPS10 is modeled as 2 regulators]

Changes from v3:
* Changed the compatible type to ti,palmas-usb-vid

Changes from v2:
fix vbus-supply value after SMPS10 is modeled as 2 regulators. This is needed
after SMPS10 is modeled as 2 regulators.
[1] models SMPS10 as 2 regulators.
[2] splits the SMPS10 node into two to represent the 2 regulators.
