Subject: [PATCH v3] arm64: dts: qcom: sdm630: Add support for modem remoteproc

Modem subsystem in SDM630/660 is similar to MSM8998 and
device tree node for it is based on the one from msm8998.dtsi.

Signed-off-by: Alexey Minnekhanov <alexeymin@...tmarketos.org>

V3: Use memory-region property to specify memory regions, instead
    of using "mba" and "mpss" subnodes.
