While writing to an event device allows to set repeat rate for an
individual input device there is no way to retrieve current settings
so we need to ressurect EVIOCGREP. Also ressurect EVIOCSREP so we
have a symmetrical interface.

Providing more accurate coordinates for thumb press requires additional
steps in the filtering logic:

- Ignore samples found invalid by the debouncing logic, or the ones that
  have out of bound pressure value.
- Add a parameter to repeat debouncing, so that more then two consecutive
  good readings are required for a valid sample.

X touchscreen drivers that don't interpret the designated pen up message
assume a pen up event from a pressure value 0. For these we generate a
pressure 0 message along with the pen up message.

The pen down IRQ will toggle during each X,Y,Z measurement cycle.
Even though the IRQ is disabled it will be latched and delivered
when after enable_irq. Thus in the IRQ handler we must avoid
starting a new measurement cycle when such an "unwanted" IRQ happens.
Add a get_pendown_state platform function, which will probably
determine this by reading the current GPIO level of the pen IRQ pin.

Move the IRQ reenabling from the SPI RX function to the timer. After
the last power down message the pen IRQ pin is still active for a
while and get_pendown_state would report incorrectly a pen down state.

When suspending we should check the ts->pending flag instead of
ts->pendown, since the timer can be pending regardless of ts->pendown.
Also if ts->pending is set we can be sure that the timer is running,
so no need to rearm it. Similarly if ts->pending is not set we can
be sure that the IRQ is enabled (and the timer is not).

SNES gamepads and mice share the same type of interface so they both can be
connected to the parallel port using a simple interface.  Adding mouse
support to a gamepad driver may sound funny at first, but doing so in this
case makes it possible to connect and SNES gamepads and mice at the same
time, on the same port.
