No iMX platforms have supported ATAG-based booting. They have however re-used the CONFIG_SERIAL_TAG option as a way to enable support of reading the OTP fuses and setting the serial# environment variable in some cases. Change the warp7 support to use this symbol, use this for updating the rest of the imx7 code, and update the imx8 conditionals.
