Currently the ppc-of driver uses the compatibility string
"usb-ehci". This means platforms that use device-tree and implement an
EHCI compatible interface have to either use the ppc-of driver or add
a compatible line to the ehci-platform driver. It would be more
appropriate for the platform driver to be compatible with "usb-ehci"
as non-powerpc platforms are also beginning to utilise device-tree.

This patch merges the device tree property parsing from ehci-ppc-of
into the platform driver and adds a "usb-ehci" compatibility
string. The existing ehci-ppc-of driver is removed and the 440EPX
specific quirks are added to the ehci-platform driver.

This patch is also out of date.  The compatibility string used by the
ehci-platform driver is "generic-ehci".

Ok. I will switch to using "generic-ehci" in the Akebono device tree.

There remains the question of whether to merge ehci-ppc-of into
ehci-platform.  This would be a rather invasive change, but I suppose
we could do it.  With adjustments along the lines suggested by Mark
Rutland.

As I can use "generic-ehci" to support Akebono I will drop this patch. I can 
look at merging ehci-ppc-of at some later date if desired (thanks Mark & Tony 
for reviewing though).
