[v3,0/4] media: si2157: rework firmware load logic

Message

As pointed bt Robert, if there's already a firmware for si2157 at
/lib/firmware, it is preferred to use it, instead of the default firmware.

Yet, when this is missed, the driver may still work. That's the case,
for instance, of the devices explicitly flagged with dont_load_firmware
(currently, Terratec Cinergy TC2).

So, rework the firmware logic in a way that it will emit a warning for
devices that are using the eeprom firmware and may not work well
with it.

Compile-tested only.

v3:
 - Rename some data structs;
 - Better handle the cases where the ROM is unknown.

v2:
 - added a patch to allow supporting different firmwares depending on
   the device's reported ROM ID.
