drm: prefer DRM_MODE_FMT/ARG over drm_mode_debug_printmodeline()

We have DRM_MODE_FMT and DRM_MODE_ARG() macros to allow unified debug
printing of modes in any printk-formatted logging. Prefer them over
drm_mode_debug_printmodeline().

This allows drm device specific logging of modes, in the right drm debug
category, and inline with the rest of the logging instead of split to
multiple lines.
