arm64: dts: ti: k3-am64-main: Add ELM (Error Location Module) node 



The ELM module is used for GPMC NAND accesses for detecting
and correcting errors during reads due to NAND bitflips errors.

4-, 8-, and 16-bit error-correction levels are supported using
the BCH (Bose-ChaudhurI-Hocquenghem) algorithm.
