[ar71xx] PCI changes from ar71xx in openwrt

[Adrian Chadd]

Hi,

I've noticed that the ar71xx PCI code in openwrt trunk is .. different.

Specifically, the "local" config stuff isn't handled in bus/slot/func
'0/0/0' - it's a different function.

This patch brings it in sync:

* break the local config writes into a new function, matching what Linux does;
* use that when doing the "PCI work around" during PCI bus attach;
* change that to a 4 byte write, rather than a 2 byte write, which
again matches what Linux does;
* change the pci read/write config to not treat 0/0/0 special and use
"local" read/write.

Any issues?
