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.
