tpudrv12.h & targets/gtm900.h: our current support is for MGC2GSMT version only
As it turns out, there exist two different Huawei-made hw platforms both
bearing the marketing name GTM900-B: one is MG01GSMT, the other is MGC2GSMT.
The two are NOT fw-compatible: aside from flash chip differences which
should be handled by autodetection, the two hw platforms are already known
to have different RFFEs with different control signals, and there may be
other differences not yet known. Our current gtm900 build target is for
MGC2GSMT only; we do not yet have a specimen of MG01GSMT on hand, hence
no support for that version will be possible until and unless someone
provides one.
