board: ti: DRA72: revC evm: Update sdram timing configuration for SR2.0

Browse Source 
DDR configuration has changes from SR1.1 based Rev-A/B version of evm
to the SR2.0 based Rev C of the EVM. Rev C evm now uses the higher
density MT41K512M8RH-125-AAT:E (IT) which is of size 2GB.

Update the DDR configuration based on data from EMIF configuration
tool 1.1.1. NOTE: we use eeprom information (ram_size) to update the
configuration.
