Frank Wang b34f8b5de0 usb: dwc3: add dis_u2_freeclk_exists_quirk
Add a quirk to clear the GUSB2PHYCFG.U2_FREECLK_EXISTS bit,
which specifies whether the USB2.0 PHY provides a free-running
PHY clock, which is active when the clock control input is active.

Refer to commit 27f83eeb6b42("usb: dwc3: add dis_u2_freeclk_exists_quirk")
in Linux Rockchip Kernel.
