[PATCH v2 0/6] TQMa7 eeprom sysinfo driver

[Alexander Feilke]

From: Alexander Feilke <alexander.feilke at ew.tq-group.com>

Integrates a new tq_eeprom sysinfo driver that reads & prints board
information during boot.

This is the basis for additional patches that will be sent along with
updates of the TQMa6 in the near future, including support for multiple
indexed sysinfo devices and VARD (variant detection) data for newer TQ SOM's.

changes in v2:
- add documentation for tq,eeprom-sysinfo dt-bindings
- use nvmem-cells instead of hardcoded offsets
- unified `tq_eeprom_serial_len` for old and new format
- replace XPL guards with $(PHASE_) in Makefile
- remove (yet) unused sysinfo IDs SYSID_RAM_SIZE and SYSID_RAM_VARIANT
- remove (yet) unused Kconfigs

Note: I got a strange unrelated error in test_ut in a previous CI run, where
dm_test_rtc_dual() returned -EINVAL, causing the test to fail. It passed in the
next run so I suppose its a race condition, but I didn't look further into it.
