[PATCH] ppc64: Remove unused rtas functions

From: Joel Schopp <jschopp@austin.ibm.com>

I was looking at rtas serialization for reasons I won't go into here.
While wandering through the code I found that two functions were not
properly serialized.  phys_call_rtas and phys_call_rtas_display_status are
the functions.  After looking further they are redundant and not
used anywhere at all.
