[PATCH 2/4] drm/mediatek: mtk_hdmi_v2: Fix non-static global variable

[Louis-Alexis Eyraud]

The struct 'mtk_hdmi_v2_clk_names' is not used outside of the
mtk_hdmi_v2.c file, so make it static to silence sparse warning:
```
drivers/gpu/drm/mediatek/mtk_hdmi_v2.c:53:12: sparse: warning: symbol
'mtk_hdmi_v2_clk_names' was not declared. Should it be static?
```
