tools: disable -Wno-type-limits

Patch series "lib/find_bit: fast path for small bitmaps", v6.

Bitmap operations are much simpler and faster in case of small bitmaps
which fit into a single word.  In linux/bitmap.c we have a machinery that
allows compiler to replace actual function call with a few instructions if
bitmaps passed into the function are small and their size is known at
compile time.

find_*_bit() API lacks this functionality; but users will benefit from it
a lot.  One important example is cpumask subsystem when NR_CPUS <=
BITS_PER_LONG.

This patch (of 12):

GENMASK(h, l) may be passed with unsigned types.  In such case,
type-limits warning is generated for example in case of GENMASK(h, 0).
