Lijo Lazar e071dce38f drm/amdgpu: Add reset control to amdgpu_device
v1: Add generic amdgpu_reset_control to handle different types of resets. It
may be added at device, hive or ip level. Each reset control has a list
of handlers associated with it to handle different types of reset. Reset
control is responsible for choosing the right handler given a particular
reset context.

Handler objects may implement a set of functions on how to handle a
particular type of reset.

prepare_env = Prepare environment/software context (not used currently).
prepare_hwcontext = Prepare hardware context for the reset.
perform_reset = Perform the type of reset.
restore_hwcontext = Restore the hw context after reset.
restore_env = Restore the environment after reset (not used currently).

Reset context carries the context of reset, as of now this is based on
the parameters used for current set of resets.

v2: Fix coding style

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.
