Subject: sh: pass along struct pci_channel

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().

Subject: sh: add init member to pci_channel data

This patch adds an init callback to struct pci_channel and makes sure
it is initialized properly. Code is added to call this init function
from pcibios_init(). Return values are adjusted and a warning is is
printed if init fails.

Subject: sh: export board_pci_channels in one place

Instead of sometimes exporting board_pci_channels[] in the board specific
code just export it in one place.

Date: Mon, 20 Apr 2009 21:11:07 +0900
Subject: sh: pci: Rewrite SH7751 PCI support to follow SH7780.

This follows the similar sort of scheme that the refactored SH7780 code
uses, using a 64MB CS3 mapping to handle the window0 case, and simply
discarding window1. This vastly simplifies the code, and allows most of
the board-specific setup to go die.

Date: Mon, 20 Apr 2009 21:17:10 +0900
Subject: sh: pci: Rename SH7751 platform ops files to fixups.

None of these contain pci_ops, only IRQ routing bits, rename them
accordingly.
