FFS dev.c: added Spansion PL032J to the "generic" table
With the discovery of first GTM900 and then Tango, it now appears that
Openmoko was not the only manuf after all who kept TI's TCS211 firmware
largely intact (as opposed to changing it beyond all recognition like
Compal, Chi-Mei and BenQ did), thus we are now getting new "alien" targets
on which we reuse the original manuf's FFS with IMEI and RF calibration
tables as if it were native. On these targets we use the original
device table for FFS, even though we previously thought that it would
never apply to any target other than dsample, leonardo and gtamodem.
We have previously added Samsung K5L33xxCAM (a new kind of multi-ID device)
to the generic table to support its use in Huawei GTM900-B modules; now
we got news that some slightly older GTM900-B specimen used S71PL032J
instead, so we are now adding PL032J as well.
