powerpc: Remove remaining iSeries chunks
In commit f5339277
"powerpc: Remove FW_FEATURE ISERIES from arch code", we
removed the bulk of the iSeries code, but missed a few bits.
Remove the mschunks bits, these were only ever used on iSeries as far as I
know, and are definitely not used anymore.
Make it even clearer that phys_to_abs() is a nop, by making it a macro. We
still have a few users of this, but should clean those up.
