drm/amdgpu: add a module parameter to control the AGP aperture
Add a module parameter to control the AGP aperture. The AGP
aperture is an aperture in the GPU's internal address space
which provides direct non-paged access to the platform address
space. This access is non-snooped so only uncached memory
can be accessed.
Add a knob so that we can toggle this for debugging.
