ECAP nodes defined in the top-level AM65x SoC dtsi files are incomplete and will not be functional unless they are extended with pinmux information. (These and the EPWM nodes could be used to trigger internal actions but they are not used like that currently) As the pinmux is only known at the board integration level, these nodes should only be enabled when provided with this information. Disable the ECAP nodes in the dtsi files and only enable the ones that are actually pinned out on a given board.
