boards: st: fix STM32H5 boards DTS files coding style

Fix board DTS coding style issues to prevent they spread when a	new
board is introduced and used this DTS as example start point.

Issues addressed from Zephyr devicetree style guidelines [1]:
- Indent with tabs.
- Insert a single empty line to separate nodes at the same hierarchy level.

No functional change.
