Get rid of IO_TOKEN_TO_ADDR() and IO_ADDR_TO_TOKEN() for pSeries EEH;
the conversion to tokens is not needed now that we have __iomem
annotations to prevent drivers from dereferencing IO addresses.

The IO tokens meant that the __raw_ IO accesses wouldn't have worked,
and removing the debugging vestiges simplifies the code noticeably.
