drm/dp_dual_mode: Convert drm_dp_dual_mode_helper.c to using drm_err/drm_dbg_kms()

Next step in the conversion, move everything in drm_dp_dual_mode_helper.c
over to using drm_err() and drm_dbg_kms(). This was done using the
following cocci script:

  @@
  expression list expr;
  @@

  (
  - DRM_DEBUG_KMS(expr);
  + drm_dbg_kms(dev, expr);
  |
  - DRM_ERROR(expr);
  + drm_err(dev, expr);
  )

And correcting the indentation of the resulting code by hand.
