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.
This change makes it possible for those devices to be detected by
drivers that support the of_platform without having a custom call
for each of them in the board file.

Changes:
v2: Use the compatible field to detect devices to register (on Dale Farnsworth
suggestion).
v3: Added __initdata to variable of_mv64x60_devices (thanks to Stephen Rothwell
for pointing that out).
v4: Re-wrote the patch description.
v5: Changed the format of the email address
