dts: arm: silabs: Clean up xg29 dts files

Reformat devicetree files according to
<https://docs.zephyrproject.org/latest/contribute/style/devicetree.html>
and <https://docs.kernel.org/devicetree/bindings/dts-coding-style.html>:

 * Sort nodes by unit address or name
 * Sort properties by category and name

Add missing MPU and prortcclk nodes.
