Merge patch series "boards: siemens: iot2050: SM variant, sysinfo support, fixes...

Jan Kiszka <jan.kiszka@siemens.com> says:

This adds support for the new IOT2050 SM variant, introduces a sysinfo
driver which also permits SMBIOS support and switches the board to
OF_UPSTREAM. There are some further fixes for the boards included as well.

Not yet included is configuration support for DMA isolation via the PVU as
this depends on not yet merged DT bindings and another overlay.

[trini: This is just the first 10 patches in the series for now]
