Subject: [PATCH 1/1] arm64: dts: qcom: apq8096-db820c: Specify zap shader location

The zap shader was previously loaded from "qcom/a530_zap.mdt", which is a
symlink to "qcom/apq8096/a530_zap.mbn". Update the DTS to reference the
actual firmware file in linux-firmware directly.

This avoids relying on the symlink and ensures a more robust firmware load
path.
