drm/amd/display: Refactor mark_seamless_boot_stream()

mark_seamless_boot_stream() can be called multiple times to run
the more expensive checks in dc_validate_boot_timing().

Refactor the function so that if those have already passed once
the function isn't called again.

Also add a message the first time that they have passed to let
the user know the stream will be used for seamless boot.
