Replace the 'ath724x' to 'ar724x' in function, variable and
structure names to reflect the name of the real SoC.

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.

The declared function in this header file is used by the
ath79 platform code only. Move the header to the platform
directory.

The 'pcibios_map_irq' and 'pcibios_plat_dev_init'
are common functions and only instance one of them
can be present in a single kernel.

Currently these functions can be built only if the
CONFIG_SOC_AR724X option is selected. However the
ath79 platform contain support for the AR71XX SoCs,.
The AR71XX SoCs have a differnet PCI controller,
and those will require a different code.

Move the common PCI code into a separeate file in
order to be able to use that with other SoCs as
well.
