imx: Convert SERIAL_TAG support to ENV_VARS_UBOOT_RUNTIME_CONFIG
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.
