Devices on the VMD domain use the VMD endpoint's requester ID and have been relying on the VMD endpoint's DMA operations. The problem with this was that VMD domain devices would use the VMD endpoint's attributes when doing DMA and IOMMU mapping. We can be smarter about this by only using the VMD endpoint when mapping and providing the correct child device's attributes during DMA operations. Remove the dma_map_ops redirect.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
