Subject[PATCH] soc: qcom: apr: Don't use reg for domain id
Date
The reg property represents the address and size on the bus that a
device lives, but for APR the parent is a rpmsg bus, which does not have
numerical addresses. Simply defining #address/#size-cells to 1 and 0,
respectively, to silence the compiler is not an appropriate solution.

Replace the use of "reg" with an APR specific property.

The APR device was recently added to msm8996.dtsi, but this is still
depending on working SMMU to provide functional audio support.
