ARM: keystone2: use SPD info to configure K2HK and K2E DDR3

Browse Source 
This commit replaces hard-coded EMIF and PHY DDR3 configurations for
predefined SODIMMs to a calculated configuration. The SODIMM parameters
are read from SODIMM's SPD and used to calculated the configuration.

The current commit supports calculation for DDR3 with 1600MHz and 1333MHz
only.
