tty: serial: imx: Allow UART to be a source for wakeup
Allow UART to be a source for wakeup from low power mode.
Tested on a MX27PDK by doing:
echo enabled > /sys/devices/platform/imx21-uart.0/tty/ttymxc0/power/wakeup
echo mem > /sys/power/state
and then pressing a key in the console will wakeup the sytem.
