This is adding the timer timer tests as standard kselftests to be run by
the wrapper script...

...but this requires specific arguments to be run which the kselftest
runner won't supply.  I'd expect it to be a good default to enumerate
and test every possible device and generate a test for each.  However it
looks like this is really intended not as a standalone test but rather
as something run from within utimer-test, in that case it should be a
TEST_GEN_PROGS_EXTENDED.

Hi Mark,

Yes, the 'global-timer' application is not a standalone test and it 
should be ran by 'utimer-test'. I had to extract the timer-binding 
functionality into a different application as we can't have 
'sound/asound.h' and 'alsa/asoundlib.h' in single source due to some 
declarations overlap problems.

I'll move the 'global-timer' tool into the TEST_GEN_PROGS_EXTENDED list.

Thank you so much for the review!
