Commit Message

microchip,sparx5-cpu-syscon is not a simple syscon device - it has
children and implements simple-mfd compatible - thus it should be fully
documented in its own binding.

Context might depend on patch in Lee's MFD tree:
https://lore.kernel.org/all/171828959006.2643902.8308227314531523435.b4-ty@kernel.org/
and also further patches here depend on this one.
