Patch #1 fix Type-C switch resource leak if probe() fails.
Patch #3 add runtime PM support to avoid register access issue if the
USB controller enters into runtime suspended state, in this state
accessing USB PHY register may lack some resources. This will also
avoid regulator leak if power_on() fails.
Patch #4 add debug control register regmap
Patch #5 add imx8mq_usb_phy_drvdata drvdata for better extension
Patch #6 correct i.MX8MP USB runtime wakeup issue after introduce runtime
PM support.

Changes in v8:
- fix imx8mq_usb_phy_remove() if condition
- add "select REGMAP_MMIO" in Kconfig
- Link to v7: https://patch.msgid.link/20260729-imx8mp-usb-phy-improvement-v7-0-c385ee40ade6@nxp.com
Changes in v7:
- replase PM_RUNTIME_ACQUIRE() with PM_RUNTIME_ACQUIRE_IF_ENABLED()
- use non-devm PM runtime callback finally, because the devm version will still cause the clock
be disabled twice when probe() is failed or driver removed at device suspended state.
- Link to v6: https://patch.msgid.link/20260715-imx8mp-usb-phy-improvement-v6-0-00d95e270e4c@nxp.com
Changes in v6:
- use devm_pm_runtime_enable() to disable runtime PM if probe fails
- add imx8mq_usb_phy_drvdata drvdata and need_genpd_rpm_on flag for better extension

Changes in v5:
- not use devm runtime callback to avoid clk enable/disable imblance
