[PATCHv5][ 6/7] board: tbs2910: Enable distro_boot support.

[Denis 'GNUtoo' Carikli]

This keeps the compatibility with the old bootcmd.

The fdtfile environment variable also needed to be set to
imx6q-tbs2910.dtb to enable booting mainline kernels
otherwise with extlinux.conf it tries to load
mx6-tbs2910.dtb instead.

With arm-linux-gnueabi-gcc 9.2.0-1 from the Parabola
GNU/Linux distribution, we have the following size
differences:
- text: +2041 bytes
- data: 0 bytes
- bss: 0 bytes
- total: +2041 bytes

Changelog since v4:
-------------------
- Sorted EXTRA_ENV_SETTINGS alphabetically as requested
  BOOTENV was also moved at the begining of
  EXTRA_ENV_SETTINGS like on include/configs/colibri-imx8x.h
- Moved BOOT_TARGET_DEVICES at the end of the file as suggested
