armv7, beagle: Second SDRAM bank don;t work
since commit 3667cbeed5e3c4067e624e52a916b1ebb02c8f05 on beagle board the second sdram bank didn;t longer work. Since this patch sdram settings just get copied from bank a, but CMD_NOP, CMD_PRECHARGE, CMD_AUTOREFRESH are not executed and after that mr register is also not updated. This patch adds this for the bank b.
