sim: dv-cfi: include stdbool.h

The dv-cfi code uses the bool type but doesn't include the stdbool.h
header.  I didn't notice for Blackfin targets as the core Blackfin
header will include stdbool.h, but most targets don't do this.

Signed-off-by: Mike Frysinger <vapier@gentoo.org>

sim: dv-cfi: include common headers only

The "devices.h" header is Blackfin-specific, so trying to build dv-cfi
for any other target fails.  Include the specific hw headers this file
needs directly.
