video: enable VIDEO_ANSI and all VIDEO_BBP options

This partially reverts changes by commit 2cc393f32fd9
("video: make BPP and ANSI configs optional") since it
caused issues with other boards (missing LCD console
output on pinebook, x86 platform or sandbox). Enable
all disabled options again and opt out of not supported
color depth in board defconfigs.
