TSCADC nodes defined in the top-level AM65 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.

The commit body says, "Disable the TSCADC nodes in the dtsi files" Please can we also provide some explanation on why tscadc1 was left as okay here in a dtsi file?
