powerpc/85xx: Update fixed DDR3 timing table for P4080DS

Most of time U-boot doesn't get an exact clock number. For example, clock
900MHz may be detected as 899.99MHz. 800MHz could be 799.99MHz. Update the
table to align the desired clocks in the middle.

powerpc/85xx: Remove DATARATE_*_MHZ defines in static ddr init

Rather than having #defines DATARATE_*_MHZ, lets just match what we do on
the SPD code and convert the DDR frequency into MHZ and just compare
with a constant.

Based on patch from Poonam Aggrwal.

Adding fixed sdram setting for cornet_ds board

800, 900, 1000, 1200MT/s data rate parameters are added for fixed sdram
setting. SPD based parameters and fixed parameters can be toggled by hwconfig.
To use fixed parameters,

hwconfig=fsl_ddr:sdram=fixed

To use SPD parameters,

hwconfig=fsl_ddr:ctlr_intlv=cacheline,bank_intlv=cs0_cs1
