cpufreq: Introduce cpufreq_driver_test_flags()
commit a62f68f5ca53ab61cba2f0a410d0add7a6d54a52 upstream.
Add a helper function to test the flags of the cpufreq driver in use
againt a given flags mask.
In particular, this will be needed to test the
CPUFREQ_NEED_UPDATE_LIMITS cpufreq driver flag in the schedutil
governor.
