Jamie Lenehan bd71ab88de sh: Fix IPR-IRQ's for IRQ-chip change breakage.
The conversion from IPR-IRQ to IRQ-chip resulted in the
ipr data being allocated in a local variable in
make_ipr_irq - breaking anything using IPR interrupts.

This changes all of the callers of make_ipr_irq to
allocate a static structure containing the IPR data which
is then passed to make_ipr_irq. This removes the need for
make_ipr_irq to allocate any additional space for the IPR
information.
