drm/sun4i: virtual CMA addresses are not needed
Driver never uses virtual address of DRM CMA buffers. Switch to CMA
helpers which don't deal with virtual mapping.

This was actually already the case before commit ad408c766c
("drm/sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS for GEM operations"),
but only convenient macro at the time used helpers with virtual
mapping.

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.
