MIPS: ath79: separate common PCI code

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.

MIPS: ath79: fix broken ar724x_pci_{read,write} functions

The current ar724x_pci_{read,write} functions are
broken. Due to that, pci_read_config_byte returns
with bogus values, and pci_write_config_{byte,word}
unconditionally clears the accessed PCI configuration
registers instead of changing the value of them.

The patch fixes the broken functions, thus the PCI
configuration space can be accessed correctly.
