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.
