Hi Jason

I can live with i2c...a0 compatible string, but it has minor problems:

1) The binding Documentation says not to do it. So we are ignoring our
   own documentation.

2) It seems likely that at some point the OEM will swap to B1 revision
   SoCs. The i2c device then does not require this quirk, but we have
   hard coded in the DT file that it is required. B1 revision would
   work, but not optimally.

So i would prefer not to explicitly enable the quirk, but determine at
run time if the quirk is needed for the SoC revision it is running on.
