splash: display splash in DM_VIDEO configurations

Browse Source 
Currently for CONFIG_DM_VIDEO=y setting splashimage env variable doesn't
have any effect. Introduce a common function for both dm-video/lcd stacks,
that checks env("splashimage") and invokes bmp_display() accordingly.
For additional details please check discussion [1].
