o Move the prototype of mem_valid() from ofw_machdep.h to md_var.h.

Browse Source 
This avoids that mem.c has to include ofw_machdep.h, including
   all OFW related headers.
o  Provide a stub for OF_decode_addr(), which is used by low-level
   console drivers to obtain a tag and handle given a OFW phandle.
   This is different from sparc64, where a fake bus tag needs to be
   created explicitly.
