[PATCH v8 5/6] phy: fsl-imx8mq-usb: introduce per-variant driver data structure

From: Xu Yang <[email protected]>

Replace direct use of phy_ops pointer in of_device_id .data with a
dedicated imx8mq_usb_phy_drvdata structure. This allows per-variant
driver data to be extended in the future without changing the match
table.
