arm64: dts: ti: k3-am62: Enable ECAP nodes at the board level

Browse Source 
ECAP nodes defined in the top-level AM62x 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.
