In order to support OTG mode we need these new properties:

	- interrupt
	- nvidia,pmc
	- nvidia,phy-instance

The nvidia,phy-instance isn't strictly needed for the OTG mode since we
know that only first controller supports it in practice, but it will be
needed in general for supporting more complex hardware features that
require knowledge of the PHY offset within common registers of the Power
Management controller (PMC).

Add the new properties to the bindings.
