dt-bindings: misc: Document reg for aspeed, p2a-ctrl nodes

The P2A controller 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.
