configs/common: enable KERNEL_DEVMEM (/dev/mem)

This is required for rainbow on Turris 1.x.

added Bug High labels

My question is... is this required to have it enabled for all of our routers? Based on your description this should be required just for Turris 1.x, but /dev/mem is helpful when debugging drivers, right?
