SPI nodes defined in the top-level AM62x SoC dtsi files are incomplete and will not be functional unless they are extended with pinmux information. As the pinmux is only known at the board integration level, these nodes should only be enabled when provided with this information. Disable the SPI nodes in the dtsi files and only enable the ones that are actually pinned out on a given board.
