Power leakage: save 40mW by turning GSM on

[Harald Welte]

Hi Werner,

I just wanted to congratulate you on your work.  As we both know, those
detailed current measurements should have been done years ago.  Good to
see they finally get done.

Since GTA03 is still early, it would probably be good to buid an automated
testsuite for it.  Everything can run self-contained on the device itself,
the coulomb counter is used as current meter.

This way it would be good to test for regressions in every hardware prototype
version, and even users at some point could check if their device behaves
somehow abnormal with regard to power consumption.

Might even be something that could be used at least for a few measurements
by production testing.
