Now that the platform code is a bit leaner, we can start consolidating
the various IRQ routing implementations. There are effectively only 2
variants, and the others can use those directly.

Commit 68b42d1b548be1840aff7122fdebeb804daf0fa3 ("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 pci-sh7780 users in pci-sh7780 itself. No functional changes, in that
every platform had exactly the same implementation.

Nothing ended up using this anymore, so just kill it off.

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

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.

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().

This patch updates the board specific irq code for r7780rp. The new code is
very similar to the other highlander implementations, with the exception that
the r7780rp handles pci interrupts using IRL. To simplify the pci code and
use the same interrupt numbers as r7780mp and r7785rp we hook in to the
cpu specific pci vectors.
The pci interrupts and the push switch all work well with and without this
patch. CF and AX88796 are not ok though and the source of the problem is
unknown at this point. The AX88796 does for not detect it's proper mac
address (IPL gets it right) and the kernel hangs on CF access. As a workaround
this patch removes the CF and the AX88796 from the platform datain case of
r7780rp.

The IO access of PCI is not supported in R7780RP and the MS7780SE
board now. The support of the IO access mode of e100 and a lot of IDE
chips becomes possible by fixing the code.

This adds preliminary support for the SH7785-based Highlander board.
Some of the Highlander support code is reordered so that most of it
can be reused directly.
This also plugs in missing SH7785 checks in the places that need it,
as this is the first board to support the CPU.

Now with the ide.h mess sorted out, most of these boards
don't need their own directory. Move the headers out, and
update the driver paths.

This cleans up quite a lot of the PCI mess that we
currently have, and attempts to consolidate the
duplication in the SH7780 and SH7751 PCI controllers.
