[char-misc-next 00/12] mei: Add DMA ring

This series adds an alternative method for transferring data between the mei driver and the device via a DMA ring. The DMA ring allows transferring data in bigger chunks, up to 128K, than the HW ring 512B. The actual sizes depend on particular MEI generations. The HW ring is faster for packets that
