am335x: ddr_defs: Update EMIF parameters
EMIF parameters are calculated based on the AC timing
parameters from the SDRAM datasheet and the DDR frequency.
Current values for these paramters in AM335x U-Boot code,
though reliable, are not fully optimal. The most optimal
settings can be derived based on the guidelines published
at [1]. A pre-computed set of values with the most optimum
settings for AM335x EVM and BeagleBone can be found at [2].
