Changed the memory map to move the 2e and 2f wishbone domains into 

the 26 domain (now dedicated to the housekeeping module), with
2e0... now 261... and 2f0... now 262...  Although this is not
strictly backwards-compatible, the addresses in defs.h have been
modified so that C code remains valid with a recompile.
