No... I was misled. The shutdown function is usually called when the
driver is unlinked. But not in this case. In this case, it is simply
called when the last reference is closed. And no, you don't want to
detach the interrupt handler in that case. My bad.

Make sure that labeling is used consistently in all function headers (part 3).

drivers/input/ft5x06.c: Remove cool logic to disable polling when there there is no client waiting for read data. That was a great idea to save CPU cycles when there is nothing reading from the touchscrren but, unfortunately, does not work with readers that open the driver in non-blocking mode. So I think we just have to eat the CPUs even when there is nothing waiting for touchscreen input.

Lpcxpresso-Lpc54618 and FT5x06 driver. Some improvements in configuration and the touchscreen driver improves the behavior some. Now I get the calibration screen and detect touches (but no un-touches).

drivers/ft5x06: Add a polled mode of operation for the FT5x06 in attempt to work around the fact that the LPCXpresso-LPC54628 chose a non-interrupt pin for the FT5x06 interrupt. Driver is still not yet functional.
