Christian König f0ee63cbc5 drm/amdgpu: cleanup amdgpu_ttm_copy_mem_to_mem and amdgpu_map_buffer v2
Cleanup amdgpu_ttm_copy_mem_to_mem by using fewer variables
for the same value.

Rename amdgpu_map_buffer to amdgpu_ttm_map_buffer, move it
to avoid the forward decleration, cleanup by moving the map
decission into the function and add some documentation.

No functional change.

v2: add some more cleanup suggested by Felix

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.
