All of the formats/modifiers supported by the plane during synchronous
flips are nor supported by asynchronous flips. The formats/modifiers
exposed to user by IN_FORMATS exposes all formats/modifiers supported by
plane and this list varies for async flips. If the async flip supported
formats/modifiers are exposed to the user, user based on this list can
take decision to proceed or not and avoid flip failures during async
flips.
