[PATCH] doc: ti: k3: Fix pseudo DTS syntax

The code block does not use valid DTS syntax, but rather a pseudo
DTS syntax. Sphinx complains about this, so fix the syntax.

"
doc/board/ti/k3.rst:467: WARNING: Lexing literal_block '/dts-v1/;...};'
as "dts" resulted in an error at token: 'i'. Retrying in relaxed mode.
