[PATCH v2 2/2] soc: mediatek: mmsys: Use an array for setting the routing registers
From: Enric Balletbo i Serra
Date: Wed Mar 17 2021 - 14:18:09 EST
From: CK Hu <ck.hu@xxxxxxxxxxxx>
Actually, setting the registers for routing, use multiple 'if-else' for different
routes, but this code would be more and more complicated while we
support more and more SoCs. Change that and use a table per SoC so the
code will be more portable and clear.

Changes in v2:
- Use a default table for mt2701, mt2712 and mt8173.
- Remove the mask field from routes struct as is not needed.
