I saw that the environment could not be loaded/stored since the
synchroinzation of the device tree from linux 181d1684cae07f111
(imx8mq: synchronise device tree with linux) and then without doing a
bisect I found this commit 5d42ea553534 (ARM: dts: imx8mq-evk: Remove
u-boot,off-on-delay-us property). After removing the delay
loading/storing worked again.
