The SCP present on MT8188 does not have an L1TCM memory region, but the binding incorrectly requires one for the dual-core description of the MT8188 SCP. Remove that requirement. Also update the minimum number of reg and reg-names to 1, since as this is a multi-core SCP with no L1TCM memory, only the CFG memory region is present in the parent node.
