This file has an implicit dependency on GPIO stuff, showing
up as the following build failure:

drivers/video/bfin-lq035q1-fb.c:369:6: error: 'GPIOF_OUT_INIT_LOW' undeclared

Other more global bfin build issues prevent an automated bisect, but
it really doesn't matter - simply add in the appropriate header.
