[PATCH 2/8] dt-bindings: extcon: qcom,pm8941-misc: Add PM8921 compatible

[Alexandre MINETTE via B4 Relay]

From: Alexandre MINETTE <contact@xxxxxxxxxxx>

PM8921 exposes USB ID state through the same interrupt-based logic as
PM8941, so it can use the same Qualcomm PMIC misc extcon binding.

Unlike PM8941, PM8921 does not need a register resource for this use
case, so allow qcom,pm8921-misc without requiring reg.
