Follow the HW spec to configure the buffer cache on Gen9+
The MOCS field is used to define the cache type for the given buffer. From the SKL+, the MOCS field is interpreted as the index that is used to find the corresponding cache type in kernel driver. The current MOCS setting causes that buffer uses the wrong cache type. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Reviewed-by: Sean V Kelley <sean.v.kelley@intel.com>
