Subject: sh: Switch dynamic IRQ creation to generic irq allocator.

Now that the genirq code provides an IRQ bitmap of its own and the
necessary API to manipulate it, there's no need to keep our own version
around anymore.

In the process we kill off some unused IRQ reservation code, with future
users now having to tie in to the genirq API as normal.

Subject: sh: intc: switch irq_desc iteration to new active IRQ iterator.

There's no need to iterative over every single irq_desc when we can
already work out which IRQs have a backing descriptor via the shiny new
for_each_active_irq(). Switch to that instead.
