The asm/powernv.h header provides prototypes for functions which need to be called by non-powernv platform code. Also include it in the powernv.h that's local to the platform directory to squash some warnings about non-static functions missing prototypes. Also include powernv.h since from opal-memcons.c since it has the prototypes for the memcons wrangling functions which are used for the opal and ultravisor msglog.
