As per the FIXME this code is entirely duplicate with what is already
provided inside drm_dsc_compute_rc_parameters(), supposedly because that
function was yielding "incorrect" results while in reality the panel
driver(s?) used for testing were providing incorrect parameters.
For example, this code from downstream assumed dsc->bits_per_pixel to
contain an integer value, whereas the upstream drm_dsc_config struct
stores it with 4 fractional bits. drm_dsc_compute_rc_parameters()
already accounts for this feat while the panel driver used for testing
[1] wasn't, hence making drm_dsc_compute_rc_parameters() seem like it
was returning an incorrect result.
Other users of dsc->bits_per_pixel inside dsi_populate_dsc_params() also
treat it in the same erroneous way, and will be addressed in a separate
patch.
In the end, using drm_dsc_compute_rc_parameters() spares both a lot of
duplicate code and erratic behaviour.
