Marti Bolivar 427159bf95 zephyr: fix ffconf.h override use of STRINGIZE 
This is a "standard" macro name that we shouldn't be overriding.
Namespace this with an FFCONF_ prefix to avoid clashes with other
modules, such as the one currently observed in this twister error:

README 

This implementaion of file system is developed by ELM Chan
http://elm-chan.org/fsw/ff/00index_e.html.  

This is based on FAT file system specification.  It provides
an interface to physical storage management through its disk io
API in diskio.c. The disk io interfaces are updated to interface
with Zephyr flash memory management.
