mfd: Factor out WM831x I2C I/O from the core driver
In preparation for the addition of SPI support for the WM831x move the I2C specific code into a separate file with a separate Kconfig option so the I2C support can be excluded from the build. Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new symbol. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
