ARM: dts: msm: Remove DMA muxer resetting on msm8937, msm8953 and msm8996

HW init call during suspend/resume or idle pc restore resets the
DMA muxer to real time VBIF connection. This may cause issues, if
the rotator has already switched the muxer to non real-time. Such
invalid setting may lead to stage 1 memory fault or ping pong timeout.
Remove this reset setting and allow DMA pipes to select muxer based
on the use case.
