ENGR00123630 Set ddr clk clock according to the board IDrel_imx_2.6.31_10.05.02imx_v2009.08_10.05.02

Set DDR clock to 400Mhz on MX53-EVK with DDR2 1GByte RevB
Set DDR clock to 300Mhz on MX53-EVK with DDR2 2GByte RevA1

Remove the clock dump during boot, user can use clk command to
get the clock information. Using help clk to get the command help
