The 4 (3 external and 1 internal) i2c busses can now be specified directly via symbolic constants. The handling of the i2c_clients and the bus scanning could be improved, so that the new muxed busses also have i2c_clients for direct usage and are automatically scanned. This patch should be tested for more of the affected devices to make sure it is correct. To get rid of lines greater 80 columns one could save the tuner and demod i2c_adap in local variables.
