imx233: factor fmradio i2c and tuner power code 

Choices are limited for those: i2c is either generic software or imx233
hardware and power is either none or with a gpio. So factor ever possible
combination in a single common file and use fmradio-target.h to supply the
required parameters. This will remove a bunch of duplicate code.
