MIPS: ath79: add a common PCI registration function

Browse Source 
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.
