MLK-10039 usb: chipidea: enable usb as wakeup source if the device is connected
Enable USB as wakeup source if it is imx6sx and the usb device is connected.
We do this tricky thing for disable megafix off, since megafix control code
depends on wakeup source.
If the usb device is connected, we want the connection is
not broken, and to support HSIC device since HSIC controller
does not support hot plug.
It will not produce un-intended usb wakeup since the usb wakeup is controlled
by WIE bit in usb ctrl register, it is only enabled through /sys entry.
