[PATCH v6 1/3] phy: fsl-imx8mq-usb: add tca function driver for imx95

[Xu Yang]

The i.MX95 USB3 phy has a Type-C Assist block (TCA). This block consists
two functional blocks (XBar assist and VBus assist) and one system
access interface using APB.

The primary functionality of XBar assist is:
 - switching lane for flip
 - moving unused lanes into lower power states.

This info can be get from:
i.MX95 RM Chapter 163.3.8 Type-C assist (TCA) block.

This will add support for TCA block to achieve lane switching and tca
lower power functionality.

Changes in v2:
 - return the value of imx95_usb_phy_get_tca()
Changes in v3:
 - no changes
Changes in v4:
 - remove compatible check for imx95
 - check whether tca register region exist or not, yes means has tca,
   otherwise skip tca setup
Changes in v5:
 - no changes
Changes in v6:
 - no changes
