[PATCH v2 2/5] dt-bindings: remoteproc: mediatek: Remove l1tcm for dual-core MT8188 SCP

["Nícolas F. R. A. Prado" <nfraprado@collabora.com>]

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.
