[PATCH resend] drm/savage: Do not add framebuffer and aperture maps

From: Tormod Volden <debian.tormod at gmail.com>

Since multiple framebuffer maps are not supported any longer (commit
41c2e75e60200a860a74b7c84a6375c105e7437f) these maps would be broken,
and they are not used by the drm anyway.

Leave it to userspace to create one working map instead.

The drm driver is not required to set up fb maps, right?
For instance radeon does, but its comment says "Create mappings
for registers and framebuffer so userland doesn't necessarily
have to find them."
