ae38853249 phy: fsl-imx8mq-usb: Constify imx8mp_usb_phy_ops
The only usage of imx8mp_usb_phy_ops is to assign its address to the
data field in the of_device_id struct, which is a const void pointer.
Make it const to allow the compiler to put it in read-only memory.

f4c8116e29 phy: Add driver for mixel mipi dphy found on NXP's i.MX8 SoCs
This adds support for the Mixel DPHY as found on i.MX8 CPUs but since
this is an IP core it will likely be found on others in the future. So
instead of adding this to the nwl host driver make it a generic PHY
driver.

The driver supports the i.MX8MQ. Support for i.MX8QM and i.MX8QXP can be
added once the necessary system controller bits are in via
mixel_dphy_devdata.
