powerpc/mpic: Remove duplicate MPIC_WANTS_RESET flag
There are two separate flags controlling whether or not the MPIC is reset during initialization, which is completely unnecessary, and only one of them can be specified in the device tree. Also, most platforms in-tree right now do actually want to reset the MPIC during initialization anyways, which means lots of duplicate code passing the MPIC_WANTS_RESET flag. Fix all of the callers which currently do not pass the MPIC_WANTS_RESET flag to pass the MPIC_NO_RESET flag, then remove the MPIC_WANTS_RESET flag and make the code reset the MPIC by default.
