config: trats: trats2: extend dfu_alt_info by env update settings

This change allows updating environment stored on MMC by dfu or thor.

New setting:
- "params.bin mmc 0x38 0x8"

File params.bin can be generated by: tools/mkenvimage.
e.g. ./mkenvimage -s 4096 -o params.bin <env_text_file>

Every new env variable in text file should start with a new line.

Sample env text file:
- board/samsung/common/dfu_sample_env.txt

Requirements:
- file name: "params.bin"
- file size: 4096 Bytes - the same as CONFIG_ENV_SIZE.
  Other size will cause CRC miscalculation at boot.
