firmware: gtm900b: fix flash-based hardware variant autodetection
The original code used simplified logic whereby it assumed that
Spansion flash means MG01GSMT and Samsung flash means MGCxGSMT.
However, there exist MGC2GSMT hw variants with Spansion S71PL032J
flash in them, thus it is necessary to check the complete device ID
rather than just the flash manufacturer ID to distinguish between
MG01GSMT with 8 MiB flash (S71PL064J) and MGCxGSMT with 4 MiB flash
(S71PL032J, K5A3281CTM or K5L3316CAM).
Distinguishing between 4 MiB and 8 MiB flash chip types is also
necessary in order to configure TIFFS reader for the correct FFS
location matching that used by the original firmware, which is
in turn necessary in order to read factory RF calibration values.
Closes: OS#4769
