[PATCH 3/6] drm/modes: switch drm_mode_prune_invalid() to use struct drm_printer

[Jani Nikula]

Use device based debug logging for the mode via drm_printer.

This changes the output from the format:

[drm:drm_mode_debug_printmodeline] Modeline "6144x3456": 60 1378800 6144 6192 6224 6464 3456 3459 3464 3555 0x48 0x9
[drm:drm_mode_prune_invalid] Not using 6144x3456 mode: CLOCK_HIGH

to format:

i915 0000:00:02.0: [drm] Rejected mode: "6144x3456": 60 1378800 6144 6192 6224 6464 3456 3459 3464 3555 0x48 0x9
i915 0000:00:02.0: [drm] Rejected mode: "6144x3456": CLOCK_HIGH
