Minor improvements in ARM64 DTS for v6.11
Few cleanups and improvements which were missed by their maintainers:
1. Spreadtrum: correct PMU nodes - split per clusters.
2. HiSilicon: add dedicated compatible to syscon node ("syscon" alone is
not allowed).
3. APM: add dedicated compatible to syscon node (binding applied to MFD
tree).
