Input: gpio-keys - use hrtimer for release timer
Dealing with input, timing is important; if the button should be
released in one millisecond, then it should be done in one millisecond
and not a hundred milliseconds.
Therefore, the standard timer API is not really suitable for this task.
Convert the gpio-keys driver to use a hrtimer instead of the standard
timer to address this issue.
Note that by using a hard IRQ for the hrtimer callback, we can get rid
of the spin_lock_irqsave() and spin_unlock_irqrestore().
