2148 is 2158 without analog support. Same firmware.

I wonder if we should define own firmware for Si2148-A20 just for sure.
Olli?
But still... I have seen one case where even same revision of si2168
needs different firmware. It is not very clear for me how SiLabs uses
these firmwares, but at least it seems to be:
* There is different versions done from same chips. A10 < A20 < A30 <
B40 and so. I think that means digital logic inside of chip is changed
when they change that revision number.
* Every chip has a ROM, containing default firmware. Firmware which
driver downloads is just a patch to that ROM. ROM is updated regularly
when new patch of chips are manufactured.
So currently I have feeling it is better to define as many firmware
files as there chip revisions available, even same firmware works for
multiple chip models/versions/revisions.
