Subject: [PATCH v1 2/5] dt-bindings: soc: hpe: Add hpe,gxp-plreg

From: Nick Hawkins <nick.hawkins@....com>

The hpe,gxp-plreg binding provides access to the board i/o through the
Programmable logic interface. The binding provides information to enable
use of the same driver across the HPE portfolio.
