of/irq: Mark initialised interrupt controllers as populated

jonhunter · robherring · commit 15cc2ed6dcf9 · 2016-06-24T15:17:02.000-05:00
For interrupt controllers successfully initialised early via device-tree,
mark these interrupt controllers as populated so we don't unnecessarily
create a device and populate any platform data later on in the boot
sequence when we populate all the various platform devices.
