Add support for screen_info setups with VIDEO_TYPE_VLFB. Provide the minimum functionality of reading modes, updating and clearing the display. There is existing support for these displays provided by simpledrm with CONFIG_SYSFB_SIMPLEFB=y. Using vesadrm over simpledrm will allow for the use of additional functionality provided by VESA, such as EDID information, gamma correction and palette modes. This enhances the user experience and adds support for more display configuratons. v4: - depend on CONFIG_X86 v3: - depend on !SYSFB_SIMPLEFB (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://lore.kernel.org/r/20250401094056.32904-17-tzimmermann@suse.de
