Thierry Reding df541b658d gpu: host1x: Do not setup DMA for virtual devices 
[ Upstream commit 8ab58f6841 ]

The host1x devices are virtual compound devices and do not perform DMA
accesses themselves, so they do not need to be set up for DMA.

Ideally we would also not need to set up DMA masks for the virtual
devices, but we currently still need those for legacy support on old
hardware.

README 

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.
