Building pl172 as a module fails with:
ERROR: "of_default_bus_match_table" [drivers/memory/pl172.ko] undefined!
Because the symbol of_default_bus_match_table isn't exported by the OF core code so can't be referenced from modules. Fix this by removing the usage of of_default_bus_match_table for now. The side effect of this is that child nodes can't use "simple-bus" or "simple-mfd".

This should fix the allmod build failure introduces by the pl172 driver that Mark encountered. After this fix the driver should builds just fine as a module and there is no behavior change when boot my devkit either since none of children under pl172 uses "simple-bus/mfd" right now.
