MIPS: Yeeloong 2F: Add LID open event as the wakeup event

Yeeloong 2F netbook has an KB3310B embedded controller to manage the LID
action.  When the LID is closed or opened a SCI interrupt is sent out and
the corresponding event is saved to an EC register for later query.

Allow the LID open interrupt to wake the processor from wait mode if it is
in the suspend mode.
