gpu: nvgpu: enable DEVFREQ for Sidecar

Browse Source 
Enable DEVFREQ for OOT module unconditionally as the podgov governor
module.

linux/pm_qos is only used for downstream supported modifications
which is currently determined by CONFIG_GK20A_PM_QOS.

struct devfreq_dev_status doesn't have any field 'busy' in the upstream
driver hence enable it only for when downstream driver is in use
activated by CONFIG_GK20A_PM_QOS.

governor.h is only needed for android platforms which depend on 4.9
version of the kernel in downstream builds. Hence, added an compile
time flag to remove it for kernels versions greater than 4.9.
