* Move platform support.cpp into less generic of_support.cpp

* Add header file to support of_support.cpp
* Add support functions to obtain address and size cell lengths
* Small style cleanups
* Add support for G5 PowerPC cpus...
* Refactor memory region code to be aware of 64-bit OF addresses.
  As-is the boot loader wouldn't start on G5 systems because
  OpenFirmware memory base addresses are stored as two 32-bit
  unsigned int 'cells' vs one 32-bit unsigned int 'cell' on G3/G4.
  I removed the static struct and replaced it with a template
  and pass uint32 or uint64 depending on the address cell size.
  Thanks for the idea DeadYak!
