On the Armada 375/38x/39x SoCs, in standby mode the SoCs stay powered
and it is possible to wake-up from any interrupt sources. This patch
adds flag to the GIC irqchip driver to let linux know this.

I am planning to add these flags in the GIC driver itself and remove
this function. I will post the patch next week once merge window closes
next, so based on how that discussion proceeds you may have drop this

when I'm talking to journalists I just say "programmer" or something like that.
