MGS-2302-3 [#imx-225] disable power management for gpu profiler

GPU power management is disabled by force for performance.
The porifler will enable GPU1 power management after affinity tests.

When run openvg conformance later, GPU0 has no power management, GPU1 is
with power management and will become OFF often.
Hence this lead to GPU1 hang after openvg conformance test.
