[PATCH v4 1/2] dt-bindings: power: reset: qcom-pon: Add new compatible PMM8654AU

[Rakesh Kota]

PMM8654AU is a different PMIC from PMM8650AU, even though both share
the same PMIC subtype. Add PON compatible string for PMM8654AU PMIC
variant.

The PMM8654AU PON block is compatible with the PMK8350 PON
implementation, but PMM8654AU also implements additional PON registers
beyond the baseline. Use the PMM8654AU naming to match the compatible
string already present in the upstream pinctrl-spmi-gpio driver, keeping
device tree and kernel driver naming consistent.
