[POWERPC] Add code for removing HPTEs for parts of the linear mapping
For memory remove, we need to clean up htab mappings for the section of the memory we are removing. This implements support for removing htab bolted mappings for pSeries logical partitions. Other sub-archs may need to implement similar functionality for hotplug memory remove to work on them.
