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.

Kurobox Pro/Linkstation Pro devices use a microcontroller connected
to UART1. As most of the communication with this microcontroller is
done from userland (power button detection, fan speed ...), the setup
file has to make UART1 available from userland.

This patch implements the communication with the microcontroller on the

The mv643xx_eth platform data field ->force_phy_addr only needs
to be set if the passed-in ->phy_addr field is zero (to distinguish
the case of not having specified a phy address
(force_phy_addr = 0) from the case where a phy address of zero needs
to be used (force_phy_addr = 1.))
Also, the ->force_phy_addr field will hopefully disappear in a
future mv643xx_eth reorganisation.
Therefore, this patch deletes the ->force_phy_addr field initialiser
from all Orion board code.

If all PCI devices are working as expected, the error printks in the
various implementations of ->map_irq() doesn't really provide any
useful info. And if something is not working as expected, turning
on pci=debug gives you more useful information than the printk calls
in ->map_irq(), since the former also tells you which devices _did_
get IRQs successfully assigned. Therefore, delete these printks
entirely.

Instead of having board code poke directly into the MPP configuration
registers, and separately calling orion5x_gpio_set_valid_pins() to
indicate which MPP pins can be used as GPIO pins, introduce a helper
function for configuring the roles of each of the MPP pins, and have
that helper function handle gpio validity internally.

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.

This patch moves initialisation of EHCI/I2C/UART platform devices
from the common orion5x_init() into the board support code.
The rationale behind this is that only the board support code knows
whether certain peripherals have been brought out on the board, and
not initialising peripherals that haven't been brought out is
desirable for example:
- to reduce user confusion (e.g. seeing both 'eth0' and 'eth1'
appear while there is only one ethernet port on the board); and
- to allow for future power savings (peripherals that have not
been brought out can be clock gated off entirely).

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 "}, {".

Whereas most Orion 5x machine support code would initialise the PCI
subsystem with nr_controllers in their struct hw_pci set to 2, the
DNS323 and Kurobox Pro machine support code had nr_controllers set
to 1.
This was presumably done because on those two machines, the PCI(-X)
controller (nr == 1) isn't used, requiring initialisation of only
the PCIe controller (nr == 0.) However, not initialising the PCI(-X)
controller on boards that don't use it leads to a situation where
both the PCIe and the PCI(-X) controller think that their root bus is
zero, and it messes up IRQ assignment.
This patch changes the DNS323 and Kurobox Pro support code to always
use nr_controllers == 2.

Based on earlier work by Jon Smirl and Jochen Friedrich.
Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

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.
