[PATCH 1/4] dt-bindings: hwinfo: Add second register range for GP_SW

[Judith Mendez]

This adds a second register range in ti,k3-socinfo. This register
range can also be used to detect silicon revisions.

AM62px SR1.0, SR1.1, and SR1.2 can only be distinguished with GP_SW
registers, so increase maximum items to 2 for reg property and update
the example.
