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.
