[PATCH 13/38] dt-bindings: remoteproc: mediatek: Remove l1tcm MMIO from MT8188 dual

[AngeloGioacchino Del Regno]

Even though the MT8188 SoC's Dual-Core SCP IP is practically the
same as the one found on MT8195, it doesn't have a dedicated L1
TCM and relies only on SRAM.

Set reg/reg-names minItems to 1 globally and override it in all of
the conditionals for the SoCs that require more, and then split
the mt8195/8188 conditionals to allow specifying only the cfg MMIO
on MT8188.

Fixes: 91e0d560b9fd ("dt-bindings: remoteproc: mediatek: Support MT8188 dual-core SCP")
