[PATCH 2/6] drm/probe-helper: switch to drm device based logging

[Jani Nikula <jani.nikula@intel.com>]

Prefer drm_dbg_kms() over DRM_DEBUG_KMS() to debug log the drm device
info. Also use drm_mode_print() for drm device specific debug logging
the probed modes.

This changes the probed modes output from the format:

[drm:drm_helper_probe_single_connector_modes] [CONNECTOR:290:DP-5] probed modes :
[drm:drm_mode_debug_printmodeline] Modeline "3840x2160": 60 533250 3840 3888 3920 4000 2160 2163 2168 2222 0x48 0x9

to format:

i915 0000:00:02.0: [drm:drm_helper_probe_single_connector_modes] [CONNECTOR:290:DP-5] probed modes:
i915 0000:00:02.0: [drm] Probed mode: "3840x2160": 60 533250 3840 3888 3920 4000 2160 2163 2168 2222 0x48 0x9
