soc: mediatek: Kconfig: Add MTK_CMDQ dependency to MTK_MMSYS

The mtk-mmsys and mutex drivers do have a dependency on MTK_CMDQ,
even though both can work with *or* without it: since CMDQ support
can be enabled either as module or as built-in, it is necessary to
add a depends rule in Kconfig, so that we disallow building both
mtk-mmsys and mtk-mutex as built-in if mtk-cmdq-helper is built as
a module, otherwise obvious linker issues appear.
