[POWERPC] Fix future firmware feature fixups function failure

Browse Source 
Move firmware feature initialisation from pSeries_init_early to the
earlier pSeries_probe_hypertas so they are initialised before firmware
feature fixups are applied.

Currently firmware feature sections are only used for iSeries which
initialises the these features much earlier.  This is a bug in waiting
on pSeries.

Also adds some whitespace fixups.
