(slot, fn) pair is somewhat confusing because of ARI.
So use devfn for pci_find_device() instead of (slot, fn).

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.

As an alternative to the 3 individual handlers, there is also a simplified
io mem hook function. To be consistent, let's add an endianness parameter
there too.

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.

pci_host_data_register_io_memory and its variants are too long a bit.
So shorten them. Now they are
pci_host_{conf, data}_register_{mmio, mmio_noswap, ioport}()

This patch renames pci_addr_to_dev(), pcie_mmcfg_addr_to_dev()
to pci_dev_find_by_addr(), pcie_dev_find_by_mmcfg_addr()

Remove switch on length: we don't care about
high bits for value, so just return all ones
if no device. And add one assert().

change the first argument, void *opaque to PCIBus *s
of the pci_data_{read, write}.
They aren't used as direct callback so the argument type
don't have to be void*. So change it to the right type.

Move pci host stuff from pci.c to pci_host.c.
And add some comments.
Later pcie host bridge functions will be defined in pcie_host.c
not to bloat pci.c.

split static functions in pci_host.h into pci_host.c and
pci_host_template.h.
Later a structures declared in pci_host.h, PCIHostState, will be used.
However pci_host.h doesn't allow to include itself easily. This patches
addresses it.
pci_host.h includes functions which are instantiated in .c by including
pci_host.h with typedefing pci_addr_t.
pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio
or target_phys_addr_t for mmio in .c file.
That prevents from including pci_host.h to use PCIHostState because of
requiring type, pci_addr_t.
Its purpose to include is to instantiate io function for mmio or ioio
depending on which pci host bridge requires ioio or mmio.
To avoid including code, we always instantiate both version.
