Cover smaller genio tests (New) (canonical#1060)

* Formatted dvfs test and removed typos

* Added test for dvfs_gpu_check_governors

* Raise SystemExit only on fail

* Added serialcheck tests

* Fixed Error raise when stdout is empty

* Added spidev test

* Added pmic regulator tests

* Fixed errors in linux_ccf

 - Moved check_env_variables to function so the module can be imported without requiring them
 - Added choices for devices considered in the test
 - Test failing with wrong verify output

* Added linux ccf tests

* Update contrib/genio/bin/spidev_test.py
