The intel_dp_dsc_get_output_bpp() function outputs two lines of
unconditional logs, which was okay when it was called only once.  But
now, we also call this function from intel_dp_mode_valid(), which is
in turn called for every mode we need to validate.  This causes a lot
of useless noise.

Remove the unconditional prints to avoid spamming the logs.  Also
remove one more print that is not unconditional, but is related.
