This has the consequence of changing the section name use for head
code from ".text.head" to ".head.text".  Since this commit changes all
users in the architecture, this change should be harmless.

The se7751 was still doing the PCI fixups in its own board directory,
so we move it over to arch/sh/drivers/pci/ with the rest of the board
fixups. It has bitrotted significantly over the years, so will still
likely need a bit of work to bring back up to date.

None of these contain pci_ops, only IRQ routing bits, rename them
accordingly.
Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.

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

This moves off of the board_pci_channels[] approach for bus registration

Not all PCI channels have non-translatable memory windows, this is a
special property of the on-chip PCIC with its 0xfd00... mapping, handle
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.
