Please specify all the interrupts similar to how the binding
says to.
<1 2 0>,
<1 3 0>,
<1 4 0>,
<1 5 0>;
Also, add irq flags?

Looks unrelated. Can you drop this?

Please sort these selects alphabetically.

This is the default for CPU_V7 and so is unnnecessary.

And this is not doing much besides enabling SMP. So I would just
drop this for now or merge it with the 8974 kconfig.

These two aren't needed?

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.
