Subject: [PATCH v4 1/2] dt-bindings: interconnect: qcom,msm8998-bwmon:
 Allow 'nonposted-mmio'

From: Konrad Dybcio <konrad.dybcio@....qualcomm.com>

One of the BWMON instances on SM8750 requires that its MMIO space is
mapped specifically with the nE memory attribute.

Allow the nonposted-mmio property which instructs the OS to do so.
