[v7,00/16] add dmadev driver for idxd devices

  This patchset adds a dmadev driver and associated documentation to support
Intel Data Streaming Accelerator devices. This driver is intended to
ultimately replace the current IDXD part of the IOAT rawdev driver.

NOTE: This patchset has several dependencies:
 - v26 of the dmadev lib set [1]
 - v7 of the dmadev test suite [2]

[1] http://patches.dpdk.org/project/dpdk/list/?series=19594
[2] http://patches.dpdk.org/project/dpdk/list/?series=19599

v7:
 * rebase on above patchsets
 * add meson reason for rawdev build

v6:
 * set state of device during create
 * add dev_close function
 * documentation updates - moved generic pieces from driver doc to lib doc
 * other small miscellaneous fixes based on rebasing and ML feedback

v5:
 * add missing toctree entry for idxd driver

v4:
 * rebased on above patchsets
 * minor fixes based on review feedback

v3:
 * rebased on above patchsets
 * added burst capacity API

v2:
 * rebased on above patchsets
 * added API to check for device being idle
 * added devbind updates for DMA devices
 * fixed issue identified by internal coverity scan
