patch 37ebbcff78 ("arm: iop13xx: Use sparse irqs for MSI") moved
iop13xx over to sparse IRQ support, but this broke the build for the
msi.c file, which now has to include mach/irqs.h itself.

No need for a private allocator. The core code handles it
already.
Allocate the non MSI irqs right at boot time via machine_desc->nr_irqs
and let the sparse core handle the MSI space.

desc_handle_irq() was declared as obsolete since long ago.
Replace it with generic_handle_irq()

WARNING: arch/arm/mach-iop13xx/built-in.o - Section mismatch: reference to
.init.text:iop13xx_pcie_map_irq from .text between 'iop13xx_pci_setup' (at
offset 0x7fc) and 'iop13xx_map_pci_memory'
While fixing this warning I also recalled Adrian Bunk's recommendation to
not use inline in .c files, as 'iop13xx_map_pci_memory' is needlessly
inlined.
Removing 'inline' uncovered some dead code so that is cleaned up as well.
