powerpc/macio: Make remove callback of macio driver void returned

Browse Source 
Commit fc7a6209d5 ("bus: Make remove callback return void") forces
bus_type::remove be void-returned, it doesn't make much sense for any
bus based driver implementing remove callbalk to return non-void to
its caller.

This change is for macio bus based drivers.
