Specify a separate partition `u-boot-env` for U-Boot's env settings for the Turris Omnia board. Do this only in U-Boot's specific DTS. We do not want to do this in Linux' official DTS, because Omnia's stock U-Boot stores env at a different address, and there are still boards with stock U-Boot. In a subsequent patch will add board code that fixes Linux's DTB before booting Linux.
