[patch][rfa] Mapping base for BoardCfg::add_memory

Hi,

Some architectures have complex memory maps and so I found it necessary 
on the port I'm working with to defer the setting of the base of the 
mapping passed to BoardCfg::add_memory. The base is now explictely set 
to zero where requred, but left unset when passed to add_memory.

Tested on an internal port and on xstormy16.

ok to commit?

Dave
