    dma/cnxk: track last index return value

    Last index value might lost the order when dma stats are reset
    in between copy operations. Patch adds a variable to track the
    completed count, that can be used to compute the last index, also
    patch adds misc other changes.

    dma/cnxk: make completion ring buffer as dynamic

    Completion buffer was a static array per dma device. This would
    consume memory for max number of descriptor supported by device
    which might be more than configured by application. The change
    allocates the memory for completion buffer based on the number
    of descriptor configured by application.

    dma/cnxk: fix device reconfigure

    Multiple call to configure, setup queues without stopping the device
    would leak the ring descriptor and hardware queue memory. This patch
    adds flags support to prevent configuring without stopping the
    device.

    dma/cnxk: fix device state

    When a device is not set to a ready state, on exiting the application
    proper cleanup is not done. This causes the application to fail on
    trying to run next time.

    Setting the device to ready state on successful probe fixes the issue.

    common/cnxk: fix DPI memzone name

    roc_dpi was using vfid as part of name for memzone allocation.
    This led to memzone allocation failure in case of multiple
    physical functions. vfid is not unique by itself since multiple
    physical functions can have the same virtual function indices.
    So use complete DBDF as part of memzone name to make it unique.
