Symbols like SOFT_RESET are way too generic to be exported at large.
To avoid this, let's move the mbus bridge register defines into a
separate file and include it where needed.  This affects mach-kirkwood,
mach-loki, mach-mv78xx0 and mach-orion5x simultaneously as they all
share code in plat-orion which relies on those defines.

Some other defines have been moved to narrower scopes, or simply deleted
when they had no user.

This fixes compilation problem with mpt2sas on the above listed
platforms.

The Kurobox Pro crashes when any of the PCI controller registers
are accessed.  This patch adds a function to the Orion PCI handling
code that board support code can call to disable enumerating the
PCI bus entirely, and makes the Kurobox Pro PCI-related init code
call this function.

The Cardbus connector does not have an IDSEL signal, and Cardbus
cards are always the intended target of configuration transactions
on their local PCI bus.  This means that if the Orion's PCI bus
signals are hooked up to a Cardbus slot, the same set of PCI
functions will will appear 31 times, for each of the PCI device
IDs 1-31 (ID 0 is the host bridge).

This patch adds a function to the Orion PCI handling code that board
support code can call to enable Cardbus mode.  When Cardbus mode is
enabled, configuration transactions on the PCI local bus are only
allowed to PCI IDs 0 (host bridge) and 1 (cardbus device).

It makes no sense to do PCIe WA window setup in the individual
board support files while the decision whether or not to use the
PCIe WA access method is made in a different place, in the PCIe
support code.

This patch moves the configuration of a PCIe WA window from the
individual Orion board support files to the central Orion PCIe
support code.

More cosmetic cleanup:
- Replace 8-space indents by proper tab indents.
- In structure initialisers, use a trailing comma for every member.
- Collapse "},\n{" in structure initialiers to "}, {".

The current orion5x board ->map_irq() routines check whether a
given bus number lives on the PCIe controller by comparing it with
the PCIe controller's primary bus number.  This doesn't work in
case there are multiple buses in the PCIe domain, i.e. if there
exists a PCIe bridge on the primary PCIe bus.

This patch adds a helper function (orion5x_pci_map_irq()) that
returns the IRQ number for the given PCI device if that device has
a hard-wired IRQ, or -1 otherwise, and makes each board's
->map_irq() function use this helper function.

Various Orion cleanups:
- Unify GPL license banner format across all files.
- Unify naming of .h double inclusion guard preprocessor macros.
- Unify spelling of "PCIe" (variants seen: PCIE, PCIe, PCI-EX.)
- Various typo fixes.
- Remove __init attributes from prototypes declared in headers.
- Remove trailing comments from #endif statements.
- Mark a couple of locally-used-only structs static.
