dt-bindings: interconnect: qcom-bwmon: Add Maili cpu-bwmon compatiblegrafted

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.

+	  This option enables the Integrity Policy Enforcement LSM
+	  allowing users to define a policy to enforce a trust-based access

+	  This option specifies a filepath to an IPE policy that is compiled
+	  into the kernel. This policy will be enforced until a policy update
+	  is deployed via the $securityfs/ipe/policies/$policy_name/active
+	  interface.
+

+	  This option enables the 'dmverity_roothash' property within IPE

+	  This option enables the 'dmverity_signature' property within IPE
+	  policies. The property evaluates to TRUE when a file from a dm-verity
+	  volume, which has been mounted with a valid signed root hash,
+	  is evaluated.
+
+	  If unsure, answer Y.
+
