Subject: [PATCH] dt-bindings: soc: sti: st,sti-syscon: document codec node

st,stih407-core-syscfg syscon block comes with a child - the audio
codec, whose binding is still in TXT format.  Document the child to fix
dtbs_check validation errors, while allowing later the binding to be
converted to DT schema:

  stih410-b2260.dtb: core-syscfg@...0000: 'sti-sasg-codec' does not match any of the regexes: 'pinctrl-[0-9]+'
