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 mx6sabrelite (where ttymxc1 is the console) by doing:

echo enabled >  /sys/devices/platform/imx-uart.1/tty/ttymxc1/power/wakeup

echo mem > /sys/power/state

and then pressing a key in the console will wakeup the sytem.
