This patch adds basic board support for MSM8974 Dragonboard
which belongs to the Snapdragon 800 family.
For now, just support a basic machine with device tree.

I think the board is APQ8074 and not MSM8974.

We should change msm8974.dts to msm8974.dtsi and include it for the board.

We can do that once we have something separate/new to add to the dtsi file.

Why wait, we should just do this to start with.  Even if the msm8974-db.dts is just:

/include/ "msm8974.dtsi"

{
	model = "Qualcomm MSM8974 Dragonboard";
	compatible = "qcom,msm8974-db", "qcom,msm8974";
}

Plus, we can do things like "disable" additional cores or such in the board.dts and have the SoC one have all 4 cores, etc in it.
