[PATCH 11/13] drm/i915/debugfs: refactor intel_seq_print_mode() into intel_print_mode()

[Jani Nikula]

Pass struct drm_printer to intel_seq_print_mode() and rename to
intel_print_mode(). Use drm_printf_indent() instead of
hand-rolling. Also pass struct drm_printer to intel_panel_info().

Prefer struct drm_printer * over struct seq_file * to unify and allow
use of drm_printer helpers.
