As there are few redundant functions in board/ti/*/evm.c files, pull them to a common location of access to reuse and include the common file to access the functions. Call k3-ddrss driver through fixup_ddr_driver_for_ecc() to fixup the device tree and resize the available amount of DDR, if ECC is enabled. Otherwise, fixup the device tree using the regular fdt_fixup_memory_banks(). Also call dram_init_banksize() after every call to fixup_ddr_driver_for_ecc() is made so that gd->bd is populated correctly. Ensure that fixup_ddr_driver_for_ecc() is agnostic to the number of DDR controllers present.
