lib/s390x: move TOD clock related functions to library

The TOD-clock related functions can be useful for other tests beside the
sck test, hence move them to the library.

lib/s390x: move TOD clock related functions to library

The TOD-clock related functions can be useful for other tests beside the
sck test, hence move them to the library.

While at it, add a wrapper for stckf, express get_clock_us() with
stck() and remove an unneeded memory clobber.

lib/s390x: add CPU timer related defines and functions

Upcoming changes will make use of the CPU timer, so add some defines and
functions to work with the CPU timer.

Since shifts for both CPU timer and TOD clock are the same, introduce a
new constant S390_CLOCK_SHIFT_US for this value. The respective shifts
for CPU timer and TOD clock reference it, so the semantic difference
between the two defines is kept.

Also add a constant for the CPU timer subclass mask.

s390x: lib: Move to GPL 2 and SPDX license identifiers

In the past we had some issues when developers wanted to use code
snippets or constants from the kernel in a test or in the library. To
remedy that the s390x maintainers decided to move all files to GPL 2
(if possible).

At the same time let's move to SPDX identifiers as they are much nicer
to read.

s390x: clock and delays calculations

The hardware gives us a good definition of the microsecond,
let's keep this information and let the routine accessing
the hardware keep all the information and return microseconds.

Calculate delays in microseconds and take care about wrapping
around zero.

Define values with macros and use inlines to keep the
milliseconds interface.
