Subject: [PATCH 01/14] dt-bindings: pinctrl: aspeed: Add reg property as a hint

The pinctrl node sits under a syscon device, and can assume offsets from
the base of the syscon based on the compatible. However, for devicetree
correctness allow a reg property to be specified, which an associated
driver may choose to use to discover associated resources.
