* remote-udi.c, remote-adapt.c, remote-mm.c: Move processor_type

Browse Source 
to tm-a29k.h and a29k-tdep.c and make it an enum.
	* a29k-tdep.c (a29k_get_processor_type): New function.  Fix many
	aspects of how we detected the processor type.
	* remote-udi.c, remote-adapt.c, remote-mm.c (*_open): Call it
	rather than figuring out the type ourselves.
