Subject: drm/tegra: hdmi: Use of_device_get_match_data()
Git-commit: 5e4acd30f308be9ec6eba0b9b296210bbcf0ed3d
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Avoid some boilerplate by calling of_device_get_match_data() instead of
open-coding the equivalent in the driver.
