units: complement the set of Hz units

Currently, Hz units do not have milli, micro and nano Hz coefficients.
Some drivers (IIO especially) use their analogues to calculate
appropriate Hz values. This patch includes them to units.h definitions,
so they can be used from different kernel places.

units: change from 'L' to 'UL'

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.

At the same time convert users in header and lib folder to use new

avoid twisted indirected includes for existing users.

include/linux/units.h: add helpers for kelvin to/from Celsius conversion

Patch series "add header file for kelvin to/from Celsius conversion
helpers", v4.

There are several helper macros to convert kelvin to/from Celsius in
<linux/thermal.h> for thermal drivers. These are useful for any other
drivers or subsystems, but it's odd to include <linux/thermal.h> just
for the helpers.

This adds a new <linux/units.h> that provides the equivalent inline
functions for any drivers or subsystems, and switches all the users of
conversion helpers in <linux/thermal.h> to use <linux/units.h> helpers.
