To prepare for abstracting adding SPI support, the I2C pieces needs to be in its own moudle. This patch moves common probe code into aic32x4_probe and common removal code into aic32x4_remove. It also creates a static regmap config structure to be copied in the I2C specific driver. Signed-off-by: Jeremy McDermond <nh6z@nh6z.net> Signed-off-by: Mark Brown <broonie@kernel.org>
