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.

Overview
--------
QorIQ LS1012A FREEDOM (LS1012AFRDM) is a high-performance development
platform, with a complete debugging environment. The LS1012AFRDM board
supports the QorIQ LS1012A processor and is optimized to support the
high-bandwidth DDR3L memory and a full complement of high-speed SerDes ports.
