configs: drop CONFIG_SYS_EXTRA_ENV_RELOC

Instead of manually specifying CONFIG_SYS_EXTRA_ENV_RELOC
for every board that needs it, it shouldn't hurt to let
initr_reloc_global_data() always relocate gd->env_addr
unless we know this pointer is outside the initial binary.

To achieve this, the relocation is omitted if
CONFIG_ENV_ADDR is defined (and ENV_IS_EMBEDDED is not).
