HID: multitouch: support of hybrid finger/pen devices

Hi Guys,

this is the second iteration of the support of dual sensors (pen + touch)
devices.

There has not been a lot of changes since v1:
- use " |= " instead of " = r || " in patch 1
- introduce a factorization of input_configured() in patch 2 (which makes more sense
IMO)
- patch 4 is new, but the change is quite small (again, tested on my database)
- patch 6 has been reworked, though it's not clear if it's better
- patch 7 has been reworked, the set_bit occurs now in input_configured()

Cheers,
Benjamin
