Some DDR related structures present in fsl_ddr_dimm_params.h, fsl_ddr_sdram.h, ddr_spd.h has various parameters with camelcase naming conventions due to which code checkpatch script generates "WARNING: Avoid CamelCase".

Convert those variable names to smallcase naming convention and modify all files which are using these structures with modified structures.

Signed-off-by: Priyanka Jain Priyanka.Jain@freescale.com --- Changes for v2: Corrected CamelCase error related to twoT_en and threeT_en which got missed in v0 patch. Thanks to Prabhakar Kushwaha for helping in finding this issue.
