dm: x86: Create a driver for x86 interrupts
It seems likely that at some point we will want a generic interrupt uclass.
But this is a big undertaking as it involves unifying code across multiple
architectures.
As a first step, create a simple IRQ uclass and a driver for x86. This can
be generalised later as required.
Adjust pirq_init() to probe this driver, which has the effect of creating
routing tables and setting up the interrupt routing. This is a start
towards making interrupts fit better with driver model.
