Merge patch series "'eeprom' command improvements"

Merge patch series "'eeprom' command improvements"

Marek Behún <kabel@kernel.org> says:

This series contains improvements for the 'eeprom' command:
- refactors
- fixes
- improvements
- ability to use driver model EEPROMs (uclass UCLASS_I2C_EEPROM)
- more flexible EEPROM layout support

It should not cause any behavior change for any existing board.

This series is a dependency for some DDR issue fixes for Turris Omnia.
I will be sending that one separately.

github PR link (with CI):

- there is a failure for
    test.py for sandbox sandbox_clang
  but it seems unrelated to these changes
