[PATCH] drm/amdgpu: Add sysfs file for VBIOS

[Russell, Kent]

There is GPU Power usage reported through amdgpu_pm_info, which also has some other information as well. I'd like that in sysfs, but I am unsure if we are  allowed to due to the other information reported there.

What "power" stuff are we talking about?  The sensors interface or the pm_info or something else?

Keep in mind umr uses the sensors debugfs file in --top mode.
