drm/i915: Convert pipe_config_buffer_mismatch() to drm_printer

Utilize drm_printer in pipe_config_infoframe_mismatch() to avoid
a bit of code duplication.

print_hex_dump() doesn't know anything about the printer so
it still needs the DRM_UT_KMS check and special handling for
the loglevel. But at least we end up with a bit less copy-pasta.
