[PATCH v4 0/5] boards: siemens: iot2050: SM variant, sysinfo support, fixes & cleanups

[Baocheng Su]

This introduces a sysinfo driver which also permits SMBIOS support.

The first 10 patches of v2 have already been applied. The remaining is
solely the sysinfo driver. To maintain consistency and ease of searching
through the history, the series title remains unchanged.
