Imagis IST3038B is another variant of Imagis IST3038 IC, which has
a different register interface from IST3038C (possibly firmware defined).
This should also work for IST3044B (though untested), however other
variants using this interface/protocol(IST3026, IST3032, IST3026B,
IST3032B) have a different format for coordinates, and they'd need
additional effort to be supported by this driver.

Add support for the IST3038C touchscreen IC from Imagis, based on
downstream driver. The driver supports multi-touch (10 touch points)
The IST3038C IC supports touch keys, but the support isn't added
because the touch screen used for testing doesn't utilize touch keys.
Looking at the downstream driver, it is possible to add support
for other Imagis ICs of IST30**C series.
