dt-bindings: usb: ti,omap4-musb: convert to DT schema

Convert OMAP MUSB USB OTG Controller binding to DT schema.
Changes during conversion:
- Include "interrupts" and "interrupt-names" properties in the YAML, as
they are used by many in-tree DTS files.
- Extend the "power" property to allow the value 150 (in addition to
existing values), since this is present in several in-tree DTS examples.
- Drop the ti,hwmods property, as it is not used by any in-tree DTS files.
