Changes in v5:
- Addressed review comments:
  * Added comments explaining the necessity of 'legacy_' prefixes (hardware label collision), pre-allocated I2C aliases (future expansions), and the 'ledd1' naming convention (schematic alignment).
  * Removed the empty `&mdio0` node to comply with upstream networking subsystem guidelines.
  * Removed the redundant `&peci0` node.
  * Sorted `&kcs3` and `&lpc_ctrl` nodes in strict alphabetical order.
- Hardware/DT alignment updates:
  * Removed unpopulated sensors (adi,adt7461, infineon,tda38640, ti,ina230, ti,ina238) to accurately reflect the current board population.
  * Added the secondary flash node (flash@1 labeled "e810") under the &spi2 bus.

Changes in v4:
- Fixed capitalization: "ventura2" -> "Ventura2".
- Reordered I2C child nodes in ascending order of unit addresses.
- Enable PECI, LPC control, and KCS3 interfaces for host communication.
- Configure MCTP controller on I2C4 and enable MCTP support for specific mux channels.
- Add Infineon TDA38640 and TI INA230 power monitor nodes.
- GPIO and Pinmux cleanup for PVT:
    - Aligned gpio-line-names as requested.
    - Remove unused or non-existent GPIO line names to align with Ventura2 PVT.
    - Update specific GPIO pins to empty strings where signals were removed or consolidated.
- Adjust SGPIOM frequency to 200kHz and update signal line names.
- Enable UART3 and add serial2 alias.
