[v11,00/16] 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.

v11:
 * addressed ML feedback from Chengwen

v10:
 * meson fix to ensure Windows and BSD builds compile

v9:
 * add missing meson check for x86

v8:
 * fix compilation issues of individual patches

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

Applied (with notified fix), thanks.

Something is wrong in main branch with Windows compilation.
It was not caught before, since this series crossed the road while
Windows compilation on dma drivers passed.

I am not entirely sure on the fix, I'll post a patch to see if CI agrees.
(I still wonder how stdint.h gets included for uintX definitions, but
that's either "include luck" or my lack of coffee).
