Subject: [PATCH] [POWERPC] Do firmware feature fixups after features are
initialised
On pSeries the firmware features are not setup until ppc_md.init_early,
so we can't do the firmware feature sections fixups till after this.
Currently firmware feature sections is only used on iSeries which inits
the firmware features much earlier. This is a bug in waiting on
pSeries.
