Blackfin: handle BF561 Core B memory regions better when SMP=n

Rather than assume Core B is always run with caches turned on, let people
load into any of the on-chip memory regions.  It is their business how the
SRAM/Cache regions are utilized, so don't prevent them from being able to
load into them.
