system: Allow restricting the legacy ld/st_phys() 'native-endian' API

Browse Source 
Guard the native endian APIs we want to remove by surrounding
them with TARGET_NOT_USING_LEGACY_NATIVE_ENDIAN_API #ifdef'ry.

Since all targets can check the definition, do not poison it.

Once a target gets cleaned we'll set the definition in the
target config, then the target won't be able to use the legacy
API anymore.
