In this patch series, these drivers expose format modifiers based on the

The LINEAR modifier is advertised as default if a driver doesn't specify
modifiers. However, there are legacy drivers such as radeon that do not
support modifiers but infer the actual layout of the underlying buffer.
Therefore, a new flag not_support_fb_modifires is introduced for these
legacy

replaced with fb_modifiers_not_supported and removed.
