General cleanup of the driver, removing unused functions and sysfs interface
since it was agreed upon that userspace wouldn't control the backlight.
Adding delay when turning on the microcontroller to wait for the chip to be
ready.

Switching to edge triggered interrupt.
This requires extra code to ignore spurious interrupts while powering on.

Cypress made this change to ensure reported key statuses don't get out of
sync between user-space and the controller.
The basic idea is to read the status of all the keys at once on each read and
send all the relevant key states to user-space.

Fixing the version check in the touchkey driver to account for older firmware
revs 0xc4 and above.
