drm/i915/dp_mst: Use output_format to get the final link bpp
The final link bpp used to calculate the m_n values depend on the
output_format. Though the output_format is set to RGB for MST case and
the link bpp will be same as the pipe bpp, for the sake of semantics,
lets calculate the m_n values with the link bpp, instead of pipe_bpp.
