[PATCH v2 3/3] arm64: dts: qcom: Specify dload address for msm8916 and msm8996

On msm8916 and msm8996 boards a secure io-write is used to write the
magic for selecting "download mode", specify this address in the
DeviceTree.

Note that qcom_scm.download_mode=1 must be specified on the kernel
command line for the kernel to attempt selecting download mode.
