Input: pixcir_i2c_ts: Add Type-B Multi-touch and DT support

Hi Dmitry,

These are the pending patches that didn't go through in the 3.16 merge window. Please queue them for -next. Thanks.

The series does the following
- convert to Type-B multi touch protocol
- support upto 5 fingers with hardware supplied tracking IDs
- device tree support

Tony,

The last 2 patches fix the touch screen size property in the device tree since we now use the unified touch screen properties.

cheers,
-roger

Changelog:

v7:
- Rebased on 3.16-rc1.

v6:
- Use unified touchscreen bindings.
- Update pointer math i.e. bufptr += 4 instead of &bufptr[4];

v5:
- Changed ts->exiting flag to ts->running in patch 2.
- Don't call pixcir_stop() from .suspend() if wakeup is required.
