As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
keep bisectability.

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: Add support for Si2147-A30 tuner

This patch adds support for Si2147-A30 tuner. Fairly trivial, no firmware needed for this tuner. However, command 14 00 02 07 01 00 seems to be mandatory. On Si2157 and Si2158 the value 0x0100 is the default value, so this patch does not impact the existing tuners/devices. On Si2147 the default is 0x0000 and I can't get a lock with that value.

While here, fix the return length of the previous set command to 4 bytes.
