colibri_imx7: prepare environment to boot the M4 core

Create a variable to boot the Cortex-M4 core. By default, the command
is not doing anything. Flash a firmware into the UBI volume using:

Colibri iMX7 # ubi part ubi
Colibri iMX7 # fatload ${interface} 0:1 ${loadaddr} hello_world.bin
Colibri iMX7 # ubi write ${loadaddr} m4firmware ${filesize}

And set the command to boot the firmware automatically:

Colibri iMX7 # setenv m4boot 'ubi read 0x7F8000 m4firmware && bootaux 0x7F8000'
