There are also a few boards with DM_VIDEO and LCD both enabled:
$ git grep CONFIG_LCD `git grep DM_VIDEO=y configs/ | awk -F : '{print $1}'`
configs/peach-pi_defconfig:CONFIG_LCD=y
configs/peach-pit_defconfig:CONFIG_LCD=y
configs/snow_defconfig:CONFIG_LCD=y
configs/spring_defconfig:CONFIG_LCD=y
so using y if !DM_VIDEO would disable the command for them.

I'd like to reduce the defconfig size, so v2 patch uses
"default y if LCD" to auto-select the command (compatibility for
existing CONFIG_LCD users). For other configurations the command
should be enabled in defconfig by users, when needed.
