[media] mceusb: add a per-model structure

The previous logic needed duplicate USB table structs, one to store
the list of the devices, and 3 sets of other structs, to store the
quirks list.

With this change, devices that require expecial quirks just need to
have a .driver_info = <quirk entry>.

It also allows adding some extra quirks, like per-model RC tables.

As a bonus, this patch reduced in 10% the data segment size:

   text    data     bss     dec     hex filename

  15438    4496       4   19938    4de2 new/mceusb.ko
