Georgi: Since Greg wants to allow compiling the interconnect support as
a module [1], should I change CONFIG_INTERCONNECT to be a module? Or
leave this as is? The GPU works fine with interconnect as a module on my
phone. I know it's more for the cpufreq case.

Andy/Bjorn: This series didn't get picked up for this upcoming merge
window. If it's too late for this window (which is fine), then I'll
hold off on resubmitting this until rc4 since I'll most likely have
more device tree changes by then.
