Subject: soc: mediatek: Prepare MMSYS for DDP routing using function call

The following series are intended to prepare the mtk-mmsys driver to
allow different DDP (Data Display Path) function call per SoC.

base change:
https://patchwork.kernel.org/project/linux-mediatek/patch/[email protected]/

Change since v2:
- fix review issue in v2
- add 8183 mmsys function call
- add 8192 new component
- add 8192 mmsys function call

Subject: [PATCH v3, 2/8] soc: mediatek: mmsys: Use function call for setting the routing registers

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 function call per SoC so the
code will be more portable and clear.

mtk_mmsys_ddp_mout_en() could write register inside it rather than
return value and write register in mtk_mmsys_ddp_connect(). So you
could do ovl_mout_en() in mtk_mmsys_ddp_mout_en().

Chun-Kuang.
