arm64: dts: ti: k3-am64: Enable TSCADC nodes at the board level

TSCADC nodes defined in the top-level AM64 SoC dtsi files are incomplete
and may not be functional unless they are extended with pinmux and/or
device information.

Disable the TSCADC nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.
