Tim Harvey edbcf8e359 phy: phy-imx8mq-usb: Add support for i.MX95 USB3 PHY ...

Add initial support for i.MX95 USB.30 PHY, which is similar to
the i.MX8MQ and i.MX8MP USB PHY.

The i.MX95 USB3 PHY has a Type-C Assist block (TCA) consisting of two
functional blocks (XBar assist and VBus assist) and is documented
in the i.MX95 RM Chapter 163.3.8 Type-C assist (TCA) block.

Instead of relying on an external MUX for Type-C plug orientation the
XBar can handle the flip internally.

Add initial support for i.MX95 by:
 - allowing the driver to be enabled i.MX95
 - resetting the XBar
 - configuring the TCA in System Configuration mode (which was determined
   to be necessary to enable the PHY in device-mode)

Follow-on support will need to be added to steer the XBar based on
either board design (if only one pair is brought out) or if used with a
Type-C controller.
