Add support for PMIC8XXX power key driven over dedicated

I am very sorry for misleading Trilok and you earlier but I think this
kind of transformation should be done in your userspace framework. Have
the driver emit KEY_SCREENLOCK and have userspace initiate device
shutdown if it detects that KEY_SCREENLOCK is pressed for longer than X
seconds.
After giving this a further thought, I agree that this handling should
be in the userspace. I will submit a new patch with the changes.
Thanks.
Thank you,
