Turbo mode allows jobs to run at higher frequencies,
potentially improving performance for demanding workloads.
The change also adds the IVPU_TEST_MODE_TURBO_DISABLE flag

The IVPU_TEST_MODE_TURBO mode has been renamed to

This is going to break the struct size on compat. You probably need a
__u32 reserved to maintain 64-bit alignment.
