Convert the keyscan portion of the Holtek HT16K33 driver to adhere to the kscan API instead of the GPIO API. When this driver was introduced the kscan API was not present. The keyscan driver was therefore implemented as a GPIO interrupt driver. Signed-off-by: Henrik Brix Andersen <henrik@brixandersen.dk>
