powerpc/eeh: Remove unused inline functions

pseries_eeh_init_edev() is used exclusively in eeh_pseries.c, make it
static and remove unused inline function.

pseries_eeh_init_edev_recursive() is only called from files build wich
CONFIG_HOTPLUG_PCI_RPA which depends on CONFIG_PSERIES and CONFIG_EEH,
so can remove the unused inline version.
