[PATCH 56/62] ARM: samsung: select I2C where needed for PMIC

[Arnd Bergmann]

The OSIRIS machine cannot build without I2C and
TPS65010 both enabled unconditionally.

The SMDK6410_WM1190_EV1 and SMDK6410_WM1192_EV1 add-on
cards already select MFD_WM*_I2C.

In each case, failing to enable CONFIG_I2C results in a
build or link error, so most consistent solution is to
ensure that it is impossible to disable those options.

It would be nice to leave CONFIG_I2C as user-selectable,
but doing that properly would require more work.
