dt-bindings: usb: Convert OMAP OHCI/EHCI bindings to schema 

The OMAP OHCI and EHCI USB host bindings follow the generic binding, so
add the compatibles and remove the old txt binding docs.

The examples in omap-usb-host.txt don't match actual users, so update
them dropping the fallback compatible.

OMAP HS USB EHCI controller
This device is usually the child of the omap-usb-host
Documentation/devicetree/bindings/mfd/omap-usb-host.txt
Required properties:
- compatible: should be "ti,ehci-omap"
- reg: should contain one register range i.e. start and length
- interrupts: description of the interrupt line
Optional properties:
- phys: list of phandles to PHY nodes.
This property is required if at least one of the ports are in
PHY mode i.e. OMAP_EHCI_PORT_MODE_PHY
To specify the port mode, see
Documentation/devicetree/bindings/mfd/omap-usb-host.txt
Example for OMAP4:
usbhsehci: ehci@4a064c00 {
compatible = "ti,ehci-omap";
reg = <0x4a064c00 0x400>;
interrupts = <0 77 0x4>;
