drm/amd/display: add more checks to validate seamless boot timing
[why] we found using an active DP to HDMI panel that we weren't validating dp_pixel_format and hardware timing v_front_porch, causing screen to blank and/or corrupt while attempting a seamless boot. [how] added checks during dc_validate_seamless_boot_timing for these values Signed-off-by: Martin Leung <martin.leung@amd.com> Reviewed-by: Anthony Koo <Anthony.Koo@amd.com> Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
