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?
