Milton Miller 199f45c45e powerpc/xics: Reduce and comment xics IPI use of memory barriers
A single full sync (mb()) is requrired to order the mmio to the qirr reg
with the set or clear of the message word.  However, test_and_clear_bit
has the effect of smp_mb() and we are not doing any other io from here,
so we don't need a mb per bit processed.
