This can be avoided by calling the 'ar724x_pci_add_data'
function from the board specific setup code. However it
makes no sense to use that function for every board,
especially when the board does not needs to set the
platform_data field of any PCI device.
The patch allows the board setup code to specify a board
specific function if that is required.

Remove a superfluous ifdef around an include. Also
reorganize the board setup code a bit, so another
ifdef can be removed.

The Ubiquiti XM board setup code uses an invalid
IRQ number, because it if above of NR_IRQS. This
leads to failed 'request_irq' calls:
ath9k 0000:00:00.0: request_irq failed
ath9k: probe of 0000:00:00.0 failed with error -22
Preserve some IRQ numbers for the built-in IRQ
controller of PCI host controllers in the
AR71XX/AR724X SoCs, and use the correct IRQ
number in the board setup code.

The current code unconditionally registers the AR724X
specific PCI controller, even if the kernel is running
on a different SoC.
Add a common function for PCI controller registration,
and only register the AR724X PCI controller if the kernel
is running on an AR724X SoC.
