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.

# This Motorola W220 phone has a single-bank flash chip on nCS0 and
# XRAM on nCS3 instead of the usual nCS1.  The timings are unknown,
# so we set a conservative WS=4.  The flash is 8 MiB, so we need to
# enable ADD22.
