Patchset "ARM: orion: Refactor the MPP code common in the orion
platform" broke at least Orion5x based platforms. These platforms have
pins configured as GPIO when the selector is not 0x0. However the
common code assumes the selector is always 0x0 for a GPIO lines. It
then ignores the GPIO bits in the MPP definitions, resulting in that
Orion5x machines cannot correctly configure there GPIO lines.

The Fix removes the assumption that the selector is always 0x0.
In order that none GPIO configurations are correctly blocked,
Kirkwood and mv78xx0 MPP definitions are corrected to only set the
GPIO bits for GPIO configurations.

This third version, which does not contain any whitespace changes,
and is rebased on v3.3-rc2.

mv78xx0 and kirkwood use identical mpp code.

It should also be possible to rewrite the orion5x mpp to use this
platform code.

This patch is composed of two new files :

- mpp.c which is mainly inspired by the same file as in mach-kirkwood

- mpp.h that is written from the documentation provided by Marvell
http://www.marvell.com/products/processors/embedded/discovery_innovation/HW_MV78100_OpenSource.pdf

Moreover, due to some implementation problem, I have
defined some MPPX_UNUSED that offer developers the possibility
to SET MPP to some unused value (such as for Buffalo WXL).

Note: This patch doesn't support MV78200 yet (only 78100 MPP lines have
been written)
