fc-loadtool help: improve language regarding 16 MiB flash chips In FC project history, 16 MiB flash originally meant Pirelli DP-L10. Then we got FCDEV3B with the same flash (our own design), but now we are discovering more Calypso devices that used such large flash, both late Calypso era (Sony Ericsson K2x0) as well as much earlier ones (FIC FLUID devices.txt file with 2004 dates, Leonardo+ rev 5). Hence we need to migrate to more generic or neutral language in associated documentation, without giving elevated status to specific examples that drove our early project history.

# 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.
