[patch] sim: bfin: ebiu_amc: push down hardcoded base addresses


To make it easier to support ebiu banks at other addresses, move the base to a 
runtime parameter rather than structure.  Future work will make this more 
dynamic, but I'm waiting for more details first.

	* dv-bfin_ebiu_amc.c (struct bfin_ebiu_amc): Add bank_base.
	(bfin_ebiu_amc_write_amgctl): Replace BFIN_EBIU_AMC_BASE with
	amc->bank_base.
	(bfin_ebiu_amc_finish): Assign BFIN_EBIU_AMC_BASE to amc->bank_base.
