[PATCH v6 13/14] drm/atomic: Use debug category printer for atomic state printer

[Sean Paul]

From: Sean Paul <seanpaul at chromium.org>

The atomic state is printed if the DRM_UT_STATE is active, but it's
printed at INFO level. This patch converts it to use the debug
category printer so:

a- it's consistent with other DRM_UT_STATE logging
b- it's properly routed through drm_trace when introduced

Signed-off-by: Sean Paul <seanpaul at chromium.org>
