Add a KUnit test for the cs-amp-lib library. This has test cases for cs_amp_get_efi_calibration_data() and cs_amp_write_cal_coeffs(). A KUNIT_STATIC_STUB_REDIRECT() has been added to cs_amp_get_efi_variable() and cs_amp_write_cal_coeff() so that the KUnit test can redirect these to test harness functions. Much of the testing involves invoking the same function with different parameters, i.e. the number of amps and the amp index within the array. This uses parameterization rather than looping. The idea is to avoid looping over configurations within one test case as that has a higher chance of having a bug that doesn't actually test all the expected cases. Having the test run exactly one configuration, and then tear-down, is less prone to accidentally skipped configurations.
