ti,am654-serdes-ctrl is not a simple syscon device - it has children -
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.
