This patch fixes a bug in the SDRAM initialization code for the TQM5200. The hi_addr bit is now set correctly. Without this patch the hi_addr bit is always set to 1, if the second flash bank is not populated.

For other MPC5200 boards a correspondig patch has already been applied some time ago, see commit a63109281ad41b0fb489fdcb901171f76bcdbc2c.
