[PATCH] ppc64 iSeries: eliminate some unused inline functions

This patch removes from the iSeries header files a large number of inline
functions that are not used.  It also changes the only caller of a HvCallCfg
function that is outside HvLpConfig.h to its equivalent HvLpConfig function
and no longer includes HvCallCfg.h where it is not needed.
