Change the way Automatic PIO is performed in the mesgin and mesgout phases. SPIORDY should go active on any REQ of the bus, so testing for REQINIT is not necessary.  It also seems that testing for SPIORDY is more robust then REQINIT since SPIORDY comes active after REQINIT and PHASEMIS seems to take some time to come true after REQ is asserted if the phase has changed.  Of course, none of this is documented.

This should give the code savings of my original changes, without breaking the
driver on fast peripherals.
