accel/ivpu: Add turbo flag to the DRM_IVPU_CMDQ_CREATE ioctl
Introduce a new parameter to the DRM_IVPU_CMDQ_CREATE ioctl,
enabling turbo mode for jobs submitted via the command queue.
Turbo mode allows jobs to run at higher frequencies,
potentially improving performance for demanding workloads.
Also adds the IVPU_TEST_MODE_TURBO_DISABLE flag to allow test
mode to explicitly disable turbo mode requested by the application.
The IVPU_TEST_MODE_TURBO mode has been renamed to
IVPU_TEST_MODE_TURBO_ENABLE for clarity and consistency.
