fm3: fix Fujitsu MB9Ax family support 

Some MB9Ax (especially few internal SRAM model) fails programming
because of wrong SRAM basic-address on running algorithm.
Default SRAM basic-address must be 0x20000000.
This patch is fixing default SRAM basic-address and ramcode offset.
Tested on a MB9BF618T and MB9AF112K.
