The GPMC node defined in the top-level AM64x SoC dtsi files are incomplete and will not be functional unless it is extended with pinmux information. As the pinmux is only known at the board integration level, this node should only be enabled when provided with this information. Disable the GPMC node in the dtsi file. Since the ELM is made to work with the GPMC, disable it too.
