add support for mc13892 I2C based touch panel for mx35_3ds

mc13xxx touch panel support is limited to SPI based solutions
and to mc13783 based systems when it is about touch panel.

Add both I2C support to the mfd mc13xxx-core driver
and mc13892 specific support to the mc13xxx touch driver,
including calibration support for the latter.

Insert declarations needed for use with mx35_3ds development board.

Oskar Schirmer (7):
  mfd: move mc13xxx global declarations to header file
  mfd: split off mc13xxx SPI specifica from core
  mfd: add I2C handling to mc13xxx driver
  input/touchscreen: rename mc13783_ts.c
  input/touchscreen: add support for mc13892
  input/touchscreen: add calibration functionality with mc13xxx series
  arm/imx: add mc13892 I2C based touch panel support for mx35_3ds
