[PATCH] ppc32: Add rtc hooks to katana + fw bug workaround

Add rtc hooks to katana and workaround firmware bug.

- Now that the mv64xxx i2c and m41t00 i2c rtc drivers are in the source
  base, add hooks to the katana file to use that rtc.

- A recent version of the katana firmware incorrectly changes the
  mv64x60's pci vendor & device id so this patch puts back the proper
  values.

- Misc. cleanup and update of the default config file.
