[Intel-gfx] [igt-dev] [PATCH i-g-t] lib/intel_batchbuffer: Media VME kernel is valid only for Gen11

[Ye, Tony]

The kernel was design for Gen11 and the author didn't guarantee it could 
work on APL. And the binary was built with iga64 with "-p=11" option. If 
you try to build it with "-p=9" you will get "error: NoPreempt not 
supported on given platform".
As the purpose of this test was to test the asymmetric subslice of 
Gen11, I would suggest to remove the support of Gen9 and Gen10. The 
patch looks good to me.

Regards,

Tony
