[PATCH v5 1/2] dt-bindings: power: reset: qcom-pon: Add new compatible PMM8654AU

[Rakesh Kota]

PMM8654AU is a distinct PMIC variant from PMM8650AU despite sharing the
same PMIC subtype. PMM8654AU implements additional registers added to
the "hlos" register address spaces, so add qcom,pmm8654au-pon as a
fallback to qcom,pmk8350-pon to distinguish it from the baseline
PMK8350 PON implementation.

The GEN3 PON peripheral requires two register address spaces: "hlos"
for the primary PON block and "pbs" for the address needs to be
specified to facilitate software debouncing. Set minItems: 2 for reg
in the qcom,pmk8350-pon if/then constraint to enforce that both
address spaces are always present.

Changes in v5:
 - Set minItems: 2 for reg in the PMK8350 if/then block to enforce that
   both hlos and pbs address spaces are required for GEN3 PON peripherals.

Changes in v4:
 - Remove the contain for PMK8350 and new if:then for PMM8654AU as
   suggested by Krzysztof Kozlowski

Changes in v3:
 - Update the commit message.

Changes in v2:
 - Introduces PMM8654AU compatible strings as suggested by Konrad Dybcio.
