Xu Yang ee9e2b39ea phy: fsl-imx8mq-usb: keep PHY power domain runtime always-on for i.MX8MP 
On i.MX8MP, the USB PHY has a dedicated power domain that was previously
never powered off at runtime. With the introduction of runtime PM support,
the power domain will be powered off if the device is runtime suspended,
which breaks USB wakeup functionality.

To preserve wakeup functionality, mark the PHY power domain as runtime
always-on for i.MX8MP platform. To limit the behavior to i.MX8MP, add a
need_genpd_rpm_on to imx8mq_usb_phy_drvdata and set it as true for i.MX8MP.
