[PATCH v3 1/2] dt-bindings: power: supply: qcom,pmi8998-charger: add SMB5 PMICs

[Robin Snyders via B4 Relay]

From: Casey Connolly <casey.connolly@xxxxxxxxxx>

Add compatible strings for PM7250B and PM8150B, which contain the SMB5
generation of the Qualcomm switch-mode battery charger. PM7250B uses the
same charger interface and parameters as PM8150B, so require the PM8150B
compatible as its fallback.

Clarify the IIO channel descriptions because SMB5 exposes a USB current-
sense voltage while SMB2 exposes an already-converted current.
