[media] si2157: Add support for Si2146-A10 The Silicon Labs Si2146 tuner seems to work with the same driver as the Si2157, but there a few exceptions. The powerup command seems to be quite a bit different. In addition there's a property 0207 that requires a different value. Thus another entry is created in the si2157_id table to support also si2146 in this driver.

[media] si2157: support selection of IF interface The chips supported by the si2157 driver have two IF outputs (either pins 12+13 or pins 9+11). Instead of hardcoding the output to be used add an option to choose which output shall be used. As this patch changes the default behaviour, the IF interface is specified in each driver currently using si2157 driver. This is to keep bisectability.
