[POWERPC] Fix future firmware feature fixups function failure
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.
