The only reason we have bswap versions of the pci host code is that
most pci host devices are little endian. The ppc e500 is the only
odd one here, being big endian.
So let's directly pass the endianness down to the mmio layer and not
worry about it on the pci host layer.

introduce pci bridge library.
convert apb bridge and dec p2p bridge to use new pci bridge library.
save/restore is supported as a side effect.
This is also preparation for pci express root/upstream/downstream port.

Move pci bridge related code into pci_bridge.c from pci.c
for further enhancement. pci.c is big enough now, so split it out.
No code change but exporting some accesser functions.
In fact, few pci bridge functions stays in pci.c.

Convert pci_host_conf_register_mmio_noswap(x) to
pci_host_conf_register_mmio(x, 0).
Convert pci_host_conf_register_mmio(x) to
pci_host_conf_register_mmio(x, 1) for big endian hosts, all cases
happen to be BE.

It's currently not used by PPC machines. Refactor so that also Sparc64
machines can use it.
