Certain devices implement triggers as buttons rather than axes. In
particular, arcade sticks such as the HORI Real Arcade Pro.EX do not
have analog buttons.

These devices are now setup to present buttons rather than axes for
triggers.

User-space applications often also have problems with
axes-as-buttons. Activating MAP_TRIGGERS_TO_BUTTONS for a device
removes the artificial difference between buttons and triggers.

Properly handle version of the protocol where standard PS/2 packets
from trackpoint are stuffed into middle (byte 3-6) of the standard
ALPS packets when both the touchpad and trackpoint are used together.

The patch is based on work done by Matthew Chapman and additional
research done by David Kubicek and Erik Osterholm:

This driver was merged before the ep93xx core support was added
for the keypad clock and acquiring/releasing the necessary gpio's.
Now that the proper support is in the ep93xx core this driver
needs to be updated to work correctly.

Summary of changes:
  1) Remove some unused members from the platform data.
  2) Remove the custom KEY macro and use the ones available in
     <linux/input/matrix_keypad.h>
  3) Remove the keypad_{readl/writel} macros and just use
     __raw_{readl/writel} directly.
  4) Update the clk_set_rate() call to work with the core support.
  5) Cleanup the probe routine and remove some unneeded messages.
  6) Use the ep93xx core functions to acquire and release the gpio's.
  7) Fix the clk_get() call to get the keypad clock.

Since platform_device_add_data copies the passed data, the allocated
subdev_pdata is never freed. A simple fix would be to either free subdev_pdata
or put it onto the stack. But since the pcf50633 child devices can rely on
beeing children of the pcf50633 core device it's much more elegant to get access
to pcf50633 core structure through that link. This allows to get completly rid
of pcf5033_subdev_pdata.
