drm: Fix warning when building docs for scdc_helper

Fixes:
../drivers/gpu/drm/drm_scdc_helper.c:203: ERROR: Unexpected indentation.
../drivers/gpu/drm/drm_scdc_helper.c:204: WARNING: Block quote ends without a blank line; unexpected unindent.

Changes in v2:
 - Property blockquote TMDS calculations so they look pretty (Daniel)
 - Remove duplicate documentation from the header file
