Switch from DEVFS to udev for dynamic creation of device nodes for mtd
char devices.
Creates a new LDM class "mtd" with writeable and read-only devices
registered for each mtdchar device.

Patch from Catalin Marinas
This patch calculates the AFS partition length by expanding the image
length information to the nearest erase block boundary. This
eliminates the problems with JFFS2 erasing the footer.

The code was wrong in several aspects. The locking order was
inconsistent, the device aquire code did not reset a variable
after a wakeup and the wakeup handling was not working for
applications where multiple chips are sharing a single
hardware controller.
When a hardware controller is available the locking is now
reduced to the hardware controller lock and the waitqueue is
moved to the hardware controller structure in order to avoid
a wake_up_all().
The problem was pointed out by Ben Dooks, who also found the
missing variable reset as main cause for his deadlock problem.

This reworks the XIP locking to make sure no lock primitive is ever
called from XIP disabled paths even if in theory they should not
cause any reschedule. Relying on the current spinlock implementation
is rather fragile and not especially clean from an abstraction pov.
The recent RT work makes it even more obvious.

Setting the slowport to 8-bit mode is something that ought to be
done in the IXP2000 generic code, not in the MTD map driver. See
the description for ARM patch 2493/1 for an explanation.
http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=2493/1
Now that 2493/1 has been accepted and will be upstream soon, this
doesn't need to be done in the map driver anymore.
