usb: chipidea: imx: add missing USB PHY DPDM wakeup setting
[ Upstream commit 53d061c19dc4cb68409df6dc11c40389c8c42a75 ]
USB PHY DPDM wakeup bit is enabled by default, when USB wakeup
is not required(/sys/.../wakeup is disabled), this bit should be
disabled, otherwise we will have unexpected wakeup if do USB device
connect/disconnect while system sleep.
This bit can be enabled for both host and device mode.
