- 8-bit interface mode never worked properly.  The only adapter I have
  which supports the 8b mode (the Jmicron) had some problems with its
  clock wiring and they discovered it only now.  We also discovered that
  ProHG media is more sensitive to the ordering of initialization
  commands.

- Make the driver fall back to highest supported mode instead of always
  falling back to serial.  The driver will attempt the switch to 8b mode
  for any new MSPro card, but not all of them support it.  Previously,
  these new cards ended up in serial mode, which is not the best idea
  (they work fine with 4b, after all).

- Edit some macros for better conformance to Sony documentation
