This reverts commit 79b74a68486765a4fe685ac4069bc71366c538f5.
It broke booting on IBM Cell machines when the kernel is also built with
CONFIG_PPC_PS3=y.
That's because FW_FEATURE_NATIVE_ALWAYS = 0 does have an important
effect, which is to clear the PS3 ALWAYS features from
FW_FEATURE_ALWAYS.
Note that CONFIG_PPC_NATIVE has since been renamed
CONFIG_PPC_HASH_MMU_NATIVE.
Fixes: 79b74a684867 ("powerpc: Remove unused FW_FEATURE_NATIVE references")
