[PATCH] microblaze: move xlnx,compound to default bus matching

[PATCH] microblaze: move xlnx,compound to default bus matching

[Rob Herring]

Microblaze bus probing is partially broken because "xlnx,compound" is
missing from the default bus probe. Add it to the default and remove from
the Microblaze arch code.

Fixes: 44a7185c2ae6 ("of/platform: Add common method to populate default bus")

xlnx,compound is not used for ages. I see see dts files for MB in the
tree but really it is just an very old example.
