[PATCH] video: add opt out option for VIDEO_BBP selection

[Anatolij Gustschin]

Enable all BPP options by default to avoid empty video console
output (this was the case before commit 2cc393f32fd9 ("video: make
BPP and ANSI configs optional")). But also support optional selection
of only required VIDEO_BBP settings.
