[PATCH] ppc32: mv64x60 updates & enhancements

Updates and enhancement to the ppc32 mv64x60 code:
- move code to get mem size from mem ctlr to bootwrapper
- address some errata in the mv64360 pic code
- some minor cleanups
- export one of the bridge's regs via sysfs so user daemon can watch for
  extraction events
