scripts/gtm900[bp]-ffs-clean: remove some more wrong files An earlier version of GTM900-B firmware has been found in the wild that still has MFW&BMI layers included (producing files under /mmi), as well as enlarged /pcm/L[DMR]N files. These files are wrong for FreeCalypso fw and thus need to be cleaned out.
