loadtools: Mot C155 turns out to have the same flash partition quirks as the flash chip on TI's D-Sample c155.config changed to use the fixed 28f640w30b config instead of CFI, and a bit of C code in fc-loadtool had to be changed too so that flash erase-program-boot still works.

# Set WS=3 for both nCS0 and nCS1.  This configuration is used by OsmocomBB
# for all 3 Compal models (E86/88/99), and is also seen in the IDA disassembly
# listing of c115-1.0.46.E firmware contributed by Christophe Devine.

# We need to set the FFFF:FB10 register to map the flash (not the boot ROM)
# to address 0.  We need this mapping in order to be able to dump and program
# the entire flash, as for some reason the alternate nCS0 mapping at 0x03000000
# does not work on Compal phones.  (That alternate mapping works fine on
# Openmoko and Pirelli phones, though.  Perhaps the different Calypso chip
# version is the culprit, or perhaps this alternate mapping works only if the
# physical nIBOOT pin is low.)
