Empirically set cpo and clk_adjust for mpc85xx DDR2 support
This patch is against u-boot-mpc85xx.git of www.denx.com
Setting cpo to 0x9 for frequencies higher than 333MHz is verified on
both MPC8548CDS board and MPC8568MDS board, especially for supporting
533MHz DDR2.
Setting clk_adjust to 0x6(3/4 late cycle) for MPC8568MDS board is for
DDR2 on all current board versions especially ver 1.92 or later to bring
up.
