FFS code sync with Magnetite + gcc version fix
This change brings the new flash autodetection for FC and Pirelli targets
from Magnetite, and should also fix the gcc version for C1xx and gtamodem
targets, which were previously broken because they used TI's original
flash autodetect code (which operates at address 0) while the boot ROM
is mapped there.
