Marek Behún b26334824b board: freescale: various boards: Let env subsystem set gd->env_addr 
Various freescale boards set gd->env_addr to default_environment in
board_init(), conditional on CONFIG_ENV_IS_NOWHERE, but this is
redundant, since it is done by env_init() before board_init() is called.

Let the env subsystem handle this.
