[PATCH v2 0/7] toradex: fix reset and hardware detection regressions

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini at toradex.com>

This series fixes two regressions affecting multiple Toradex boards
(i.MX, TI and TEGRA based) and targets the current master, e.g. v2024.04
release.

U-Boot `reset` command is broken on all Tordex i.MX6* based SoMs since
v2023.07, this series fixes it enabling the `wdt-reboot` driver.

Since v2024.04-rc1 reading the Toradex configuration block is not working
properly anymore, the serial number and the hardware version are not read
correctly, preventing the board from functioning correctly (wrong mac address,
wrong DT, ...). This is fixed by reading the config block in `EVT_SETTINGS_R`
and adding a toradex sysinfo driver. In addition to that, we now use a random
mac address in case the config block is invalid.
