ASoC: sigmadsp: Split regmap and I2C support into separate modules

Browse source 
When the SigmaDSP module is built-in, but the I2C core is build as a module
we'll get a undefined reference:

	sound/built-in.o: In function `sigma_action_write_i2c':
		:(.text+0x5d8d4): undefined reference to `i2c_master_send'

This can happen if a audio driver that is using the regmap SigmaDSP interface is
built into the kernel, but core I2C support is build as a module. To fix this
split the SigmaDSP module into three modules, one module providing the core
infrastructure and two small modules implementing the regmap and I2C interfaces.
This allows e.g. the core infrastructure and regmap support to be built into the
kernel while I2C support can still be build as a module.
