Subject: [PATCH] soc: mediatek: mtk-mmsys: Restore MT8167 routing masks lost during merge

The original patch at
https://lore.kernel.org/all/20201027160631.608503-2-fparent@baylibre.com/
included the values for the route masks, but they got lost during merge.

Fixes: 060f7875bd23 ("soc: mediatek: mmsys: Add support for MT8167 SoC")
