Subject: [PATCH 1/4] drm/rockchip: dw_hdmi: Use modern drm_device based
 logging

Prefer drm_{err|info|dbg}() over deprecated DRM_DEV_{ERROR|INFO|DEBUG}()
logging macros.

Conversion done with the help of the following semantic patch, followed
by a few minor indentation adjustments:

@@
identifier T;
@@

(
-DRM_DEV_ERROR(T->dev,
+drm_err(T,
...)
|
-DRM_DEV_INFO(T->dev,
+drm_info(T,
...)
|
-DRM_DEV_DEBUG(T->dev,
+drm_dbg(T,
...)
)
