we need to properly restart the anx3429 after a firmware update. simply initializing the chip doesn't seem to get it to reload its firmware - at least not the portion of the chip that implements the firmware version register. so, we explicitly power down and reset the chip before reinitializing it to force it to run the new firmware. the chip also needs a 10ms "off" time so the reset is properly seen by the chip, so i did a light refactoring of the code paths that reset the anx3429. TEST=used 2 different firmware blobs and verified it switches between them during software sync.
