cpufreq: Remove cpufreq_driver check in cpufreq_boost_supported()
Currently there are three calling paths for cpufreq_boost_supported() in
all as below, we can see the cpufreq_driver null check is needless since
it is already checked before.
<path1>
cpufreq_enable_boost_support()
|-> if (!cpufreq_driver)
|-> cpufreq_boost_supported()
<path2>
cpufreq_register_driver()
|-> if (!driver_data ...
|-> cpufreq_driver = driver_data
|-> cpufreq_boost_supported()
|-> remove_boost_sysfs_file()
|-> cpufreq_boost_supported()
<path3>
cpufreq_unregister_driver()
|-> if (!cpufreq_driver ...
|-> remove_boost_sysfs_file()
|-> cpufreq_boost_supported()
