Patch series "Add Hz macros", v3.

There are multiple definitions of the HZ_PER_MHZ or HZ_PER_KHZ in the
different drivers.  Instead of duplicating this definition again and
again, add one in the units.h header to be reused in all the place the
redefiniton occurs.

At the same time, change the type of the Watts, as they can not be
negative.

This patch (of 10):

The users of the macros are safe to be assigned with an unsigned instead
of signed as the variables using them are themselves unsigned.
