    This patch adds to ioatdma and dca modules
    support for Intel I/OAT DMA engine ver.3 (aka CB3 device).
    The main features of I/OAT ver.3 are:
    * 8 single channel DMA devices (8 channels total)
    * 8 DCA providers, each can accept 2 requesters
    * 8-bit TAG values and 32-bit extended APIC IDs

    Add support for version 2 of the ioatdma device. This device handles
    the descriptor chain and DCA services slightly differently:
    - Instead of moving the dma descriptors between a busy and an idle chain,
    this new version uses a single circular chain so that we don't have
    rewrite the next_descriptor pointers as we add new requests, and the
    device doesn't need to re-read the last descriptor.
    - The new device has the DCA tags defined internally instead of needing
    them defined statically.

    Split the general PCI startup from the DMA handling code in order to
    prepare for adding support for DCA services and future versions of the
    ioatdma device.
