Subject: [PATCH 1/1] common: state: allow to overlay state backend
This allow to use overlay for state backends. I.e. on raspberry you need
use barebox with SDHCI (slow) and after linux boot it will use SDHOST driver.
But the problem now is, that the state is on SDHCI and dt-utils need it on
SDHOST. Actual it is not possible to overwrite this.
