[PATCH v3] sysdev,mv64x60: MV64x60 device bus

[Remi Machet]

Follow up of my email of 4/16/2008 titled "MV64x60 device bus".
For each mv64360 entry in the OpenFirmware database, add the 
registration of an of_bus to take care of devices connected to
the MV64x60 asynchronous devices controller.

Signed-off-by: Remi Machet (rmachet at slac.stanford.edu)
---
Use the compatible field to detect devices to register (on Dale Farnsworth
suggestion).
Added __initdata to variable of_mv64x60_devices (thanks to Stephen Rothwell 
for pointing that out).
