dt-bindings: usb: chipidea: Add i.MX95 compatible string 'fsl,imx95-usb'

The i.MX95 USB2.0 controller is mostly compatible with i.MX7D, except it
requires a second interrupt for wakeup handling. Add the compatible string
for the i.MX95 platform, add the iommus property, and enforce the
interrupt property restriction. Keep the same restriction for existing
compatible strings.
