TQM5200: fix bug in SDRAM initialization code

Browse source 
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 SDRAM bank is
not populated.

For other MPC5200 boards a correspondig patch has already been applied
some time ago, see commit a63109281a.

Forget the first patch please. I confused flash with SDRAM in
the comment ...
