gpu: nvgpu: vgpu: disable GK20A PMU support

GK20A PMU is not supported in GPU client for virtualization.  However,
to make native case and virtualization case can share same defconfig and
kernel image, we need to enable CONFIG_GK20A_PMU and
CONFIG_GK20A_DEVFREQ in defconfig.  This commit changes to detect if we
should disable GK20A PMU support in run time.
