Subject: [EXTERNAL] [PATCHv2 5/5] env: Finish migration of common ENV
options

In ARMv8 NXP Layerscape platforms we also need to make use of
CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so.
On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the

define
  to 0.

Add Kconfig entry for ENV_ADDR.
Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it.
Add ENV_xxx_REDUND options that depend on their primary option and
SYS_REDUNDAND_ENVIRONMENT
On a number of PowerPC platforms, use SPL_ENV_ADDR not

CONFIG_ENV_ADDR
  for the pre-main-U-Boot environment location.

On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
rather it being non-zero, as it will now be zero by default.
Rework the env_offset absolute in env/embedded.o to not use
CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within
ENV_IS_IN_FLASH.
Migrate all platforms.
