This change is needed in order to ensure that force config update
logic is controlled by a flag in DT/Board file/Sysfs. If config update
need to be done, then major number on device must match.
If force config update is chosen, then we override the major
version too.

This reverts commit 304d9f5172.
low power mode changes are causing issues like,delay in reponse to
touch , and controller is not recognizing the touch events as its
scan rate is also low in low power mode state . since controller is
not recognizing the touch in low power mode state , so only way
for the controller to come out of low power mode is to do multi-touch
and controller responds randomly to one of the touches and comes out
of the low power mode.

There is a possibility of receiving a release interrupt
before press when both these actions (press and release) of the
power-key are very close-by (~1-2ms) to the debounce time
of the key. Handle this case by maintaining a state variable.
Also mark the release interrupt as a wakeup source to
wakeup the system when the above mentioned abnormal case
occurs.
