[PATCH 1/1] gpio: mxc: map Both Edge pad wakeup to Rising Edge

[Shenwei Wang]

Suspend may fail on i.MX8QM when Falling Edge is used as a pad wakeup
trigger due to a hardware bug in the detection logic. Since the hardware
does not support Both Edge wakeup, remap requests for Both Edge to Rising
Edge by default to avoid hitting this issue.
