Hrm. This looks very similar to cfi_cmdset_0002.c, which we _do_ already
use with non-CFI-compliant parts. 

CFI is just the _probe_ method. We can probe chips using the JEDEC
method too, and that works just fine -- jedec_probe.c will "invoke" the
appropriate command set driver.

Can't you do the same?
