sparc32,leon: PCI patches

Hello,

I have tried to cleanup the patches as Sam/Julian suggested, I have added a PCIC_PCI and a LEON_PCI Kconfig setting which depend on PCI and (!)SPARC_LEON. Before pci_leon.h was included from pci_32.h, now the pci related stuff is declared inside of pci_32.h instead. The LEON host controller implementation specific stuff was moved into leon_pci.h in the same manner as the AMBA bus implementation on LEON in leon_amba.h.

Thank you for your time,
Daniel
