Hi Santhosh,

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.

+Moving dram_init() and dram_init_banksize() into a generic part forces
every K3 based board to use your implementation.
This also breaks the builds for phycore_am62x, phycore_am64x and also
the verdin-am62,
phycore-am62x.c:49: multiple definition of `dram_init'
phycore-am62x.c:97: multiple definition of `dram_init_banksize
