bus: mvebu-mbus: Remove name -> target, attribute mapping tables

This tables were used together with the name-based MBus window
creation API. Since that's has been removed, we can also remove
the tables.

- * target/attr values.
- *
- * For all devices except PCI, all bits of 'attr' must be
- * considered. For most SoCs, only bit 3 should be ignored (it allows
