Previously the warnings were added back at the W=1 level and above,
this now turns them on again by default, assuming that we have addressed
all warnings and again have a clean build for v4.10.

I found a number of new warnings in linux-next already and submitted
bugfixes for those. Hopefully they are caught by the 0day builder
in the future as soon as this patch is merged.

Please check if there are any remaining warnings with this
patch before applying.

The one known issue right now is commit 32cb7d27e65d ("iio:
maxim_thermocouple: detect invalid storage size in read()"), which
is currently in linux-next but not yet in mainline.

There are a couple of warnings that I get with randconfig builds,
and I have submitted patches for all of them at some point and
will follow up on them to make sure they get addressed eventually.
