[U-Boot] [PATCH 03/15] MPC85xx: Fix some settings for MPC8569MDS board

[Haiying Wang]

- Change the CONFIG_SYS_CLK_FREQ and CONFIG_DDR_CLK_FREQ to 66666666 since the
on-board oscillator's freq is 66.666MHz.
- Increase the size of malloc to 512KB because MPC8569MDS needs more memory for
malloc to support up to eight Ethernet interfaces.
- Move Environment address out of uboot thus the saved environment variables
will not be erased after u-boot is re-programmed.
