This implements a total rewrite of the rather buggy SE7722 FPGA IRQ code,
utilizing a linear irq domain as well as the generic irq chip type.
While the interaction between the two APIs is a bit clunky (ie, revmap
lookup for gc irq_base), they work well enough together that it's easy
enough to work with going forward.
While we're at it, deal with irq_mask_ack/unmask of the chained IRQ in
the demux handler to prevent smc91x screaming about spurious interrupts.
There's also some more improvement that can be made to the irqdomain code
to create backing irqdescs for the entire linear range in one bang
instead of iterating over the number of hwirqs and doing it
irq-at-a-time. This is easily dealt with at a later point, though.

Migrate Solution Engine boards to evt2irq backed hwirq lookups.

This gets rid of the arbitrary set of vectors used by the SE7722 FPGA
interrupt controller and witches over to a completely dynamic set.
No assumptions regarding a contiguous range are made, and the platform
resources themselves need to be filled in lazily.
