Merge patch series "Drop ATAGS for B&R boards"

Wolfgang Wallner <wolfgang.wallner@br-automation.com> says:

There was recently a discussion on which boards need ATAGS support.
The B&R boards which have this support enabled actualyl don't need it.
This patch series drops the settings from the relevant defconfigs.
