Subject: [PATCH v5 3/5] dt-bindings: hwmon: hpe,gxp-fan-ctrl: remove fn2 and pl registers

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

Reduce the hpe,gxp-fan-ctrl register references from 3 to 1. The
function2 (fn2) and programmable logic (pl) references are removed.
The purpose of removal being their functionality will be consumed by a
new GPIO driver.
