I tried to build an allmodconfig kernel with W=1, and the bfa
driver stuck out for having the most warnings in one file, so
I decided to send patches for all of these and make the driver
build cleanly with the extra warnings enabled.
As most warnings were for functions that lacked a 'static',
I marked them that way, and also used a script to look for
further functions that have a declaration but can also be static.
Overall, this saves around 10% of the size of the driver
module:

bfa: mark symbols static where possible
bfa: remove unused variables
bfa: rename some global variables
bfa: remove unused functions from fbbuild.c
bfa: remove more unused functions
