arm64: dts: qcom: sm6375: Hook up MPM
[ Upstream commit d3246a0cf43fd24a1986163284edd2389143809d ]
Add a node for MPM and wire it up on consumers that use it. This also
fixes a very bad and sad assumption I made when initially porting this
SoC that the downstream MPM-TLMM mappings were 1-1. That apparently
changed some time ago, so with this patch the MPM consumers will actually
be hooked up to the correct interrupt lines.
