Subject: dt-bindings: interconnect: qcom-bwmon: Add Maili cpu-bwmon compatible

Add the Qualcomm Maili SoC compatible string for the CPU bandwidth
monitor (BWMONv4). This falls back to the sdm845-bwmon compatible,
consistent with the existing pattern used by other recent SoCs such as
sm8750 and kaanapali.
