This isn't a real BAR, so prevent any attempts to move it, as we don't
wish to encourage a bus luck by overzealous PCI initialization code.

This moves the remaining common bits in to pci-lib. Thereby reducing
pci.c/pci-new.c to simple bus fixups and controller registration.

As more platforms are moved over, the old code will disappear completely
and the pci-new bits will be rolled in to pci-lib, eventually replacing
pci.c completely.

Now that the io and mem offsets are tracked accordingly, the pci-new

Not all PCI channels have non-translatable memory windows, this is a

this explicitly.

This consolidates the pci_iomap() definitions and reworks how the I/O
port base is handled. PCI channels can register their own I/O map base,
or if none is provided, the system-wide generic I/O base is used instead.

Functionally nothing changes, while this allows us to kill off lots of
I/O address special casing and lookups.

Commit 68b42d1b ("sh: sh7785lcr: Map
whole PCI address space.") changed around the semantics of how various
chip-selects are made accessible to PCI. Now that there is a single
large mapping covering from CS0-CS6, there is no longer any need to
do multi-window mapping. Subsequently, all of the differing
implementations can be consolidated in to pci-sh7780.

This consolidates all of the PCI I/O and memory window definitions across

The SH7780 PCIC contains a read-only cache line size register that we can

This reworks how the host controller is probed, and makes it a bit more
verbose in the event a new type of controller is detected. Additionally,
we also log the revision information.

This now uses the proper access sizes for the vendor/device registers,
rather than relying on a larger access that encapsulated both of them.
Not all devices support 32-bit read cycles for these registers.

The SH7780 PCI host controller implements a configuration header that
requires a fair bit of hand-holding to initialize properly. By default
it appears as a pre-2.0 host controller given the zeroed out class code,
so fix this up properly.

Some boards that happened to be using the R7780RP version of the PCIC
fixups had set this correctly, but this belongs in the standard
initialization, and is by no means board specific.

These patches rework the pci code for the sh architecture.

Currently each board implements some kind of ioport to address mapping.
Some boards use generic_io_base others try passing addresses as io ports.
This is the first set of patches that try to unify the pci code as much
as possible to avoid duplicated code. This will in the end lead to fewer
lines board specific code and more generic code.

This patch makes sure a struct pci_channel pointer is passed along to
various pci functions such as pci_read_reg(), pci_write_reg(),
pci_fixup_pcic(), sh7751_pcic_init() and sh7780_pcic_init().
