[PATCH v2 4/6] board: tq: common: add sysinfo helpers

[Alexander Feilke]

From: Nora Schiffer <nora.schiffer at ew.tq-group.com>

Add a number of helpers based on the tq_eeprom sysinfo driver and
related hardware detection features. The helpers set up the U-Boot
environment and fixup the OS Device Tree.
