[PATCH 01/10] drm/rockchip: dw_hdmi: Use of_device_get_match_data() to get match data

[Jonas Karlman <jonas@kwiboo.se>]

Change to use of_device_get_match_data() to get match data prior to
allocating private data. All current entries in the of_device_id match
table provide match data, so no functional change is intended.
