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.

+description:
+  Texas Instruments glue layer for the Mentor Graphics MUSB OTG controller.
+  Handles SoC-specific integration including PHY interface bridging(ULPI/
+  UTMI), interrupt aggregation, DMA engine coordination (internal/
+  external), VBUS/session control via control module mailbox, and
+  clock/reset management. Provides fixed hardware configuration parameters
+  to the generic MUSB core driver.
