MLK-16013-40 phy: phy-fsl-imx8mq-usb: clear COMMONONN to keep FREECLK running
COMMONONN: This signal controls whether the high-speed Bias and PLL
blocks remain powered—consuming additional current during Suspend and
Sleep modes. As imx8mq USB3 ITP&SOF have to use FREECLK, so clear
COMMONONN to be 0(valid) to make FREECLK always running, this is the
recommended setting from design team.
