The actual decision was that this needed to be converted to the driver-model.
Setting CONFIG_BOOT_MODE_REG=0 was a workaround that we used only
for 2019.1, so I could delay applying Simon’s patch until this cycle.

Please convert this into a DM driver, so we can add the driver for 2019.4.

Thanks,
Philipp.
