[PATCH v3 0/7] 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

changes in v3:
- fix fixed-layout compatible in dts
- use return value ret in sysinfo_tq_eeprom_detect
- remove unneeeded depends on !SPL_BUILD from Kconfig
- separate nvmem-layout commit to be dropped once upstream patch is accepted and
  synced. Msg-ID of V1: 20260527093719.160777-1-Alexander.Feilke at ew.tq-group.com
- commit message improvements
- docstring improvements
