Changes in V12:
 - None.

Changes in V11:
 - Add ldos directly under pm8008@8 node, remove the intermediate "regulators"
   node.

Changes in V10:
 - Regulators are added as a part of pm8008@8 device. Change bindings doc
   accordingly.

Changes in V9:
 - Remove description for reg and drop unused phandle from example.

Changes in V8:
 - This is split from pm8008.yaml binding.
