powerpc/irq: Refactor irq_soft_mask_{set,or}_return()

Browse Source 
This partialy reapply commit ef5b570d37 ("powerpc/irq: Don't
open code irq_soft_mask helpers") which was reverted by
commit 684c68d92e ("Revert "powerpc/irq: Don't open code
irq_soft_mask helpers"")

irq_soft_mask_set_return() and irq_soft_mask_or_return()
are overset of irq_soft_mask_set().

Have them use irq_soft_mask_set() instead of duplicating it.
