Gigabeat S:

  1) Rework event handling and static registration mechanism. No target-
     specific code in mc13783 driver. GPIO event driver interfaces more
     cleanly.

  2) Somewhat related - enable thread priority for bootloader which is
     desireable here (ffs is used for GPIO event enabling  anyway and that
     goes along with priority).
