Subject: [PATCH] arm64: dts: ti: k3-j721e: Enable TSCADC nodes at the board
level
TSCADC nodes defined in the top-level J721e 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.
