[U-Boot] [PATCH 2/8] powerpc/env: Correct the compilation errors when defined CONFIG_ENV_IS_NOWHERE

[Liu Gang]

When defined CONFIG_ENV_IS_NOWHERE, there will be some compilation errors:

./common/env_nowhere.o: In function `env_relocate_spec':
./common/env_nowhere.c:38: multiple definition of `env_relocate_spec'
./common/env_flash.o: ./common/env_flash.c:326: first defined here
./common/env_nowhere.o: In function `env_get_char_spec':
./common/env_nowhere.c:42: multiple definition of `env_get_char_spec'
./common/env_flash.o:./common/env_flash.c:78: first defined here
./common/env_nowhere.o: In function `env_init':
./common/env_nowhere.c:51: multiple definition of `env_init'
./common/env_flash.o:./common/env_flash.c:237: first defined here
make[1]: *** [./common/libcommon.o] Error 1
make[1]: Leaving directory `./common'
make: *** [./common/libcommon.o] Error 2

There will be a confict if defined CONFIG_ENV_IS_NOWHERE and
CONFIG_ENV_IS_IN_FLASH.
