[Blackfin] arch: rename bf5xx-flash to bfin-async-flash
- move all kconfig board settings into board resources - fixup casting style according to lkml feedback - rewrite driver so that it can handle arbitrary of instances according to the declared platform resources Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Cc: Joern Engel <joern@logfs.org> Signed-off-by: Bryan Wu <cooloney@kernel.org>
