Since commit 1aed9509b29a6 ("drm/fb-helper: Remove return value from
drm_fbdev_generic_setup()"), drm_fbdev_generic_setup() must be called
after drm_dev_register() to avoid the warning. Do that.

As usual, we can drop the drm_dev_put() and need to embed the
drm_device. Since it's so few, also go right ahead and leave
drm_device->dev_private set to NULL, so that we always use the
container_of() upcast, which is faster anyway.

The static structure aspeed_gfx_funcs, of type
drm_simple_display_pipe_funcs, is used only as an argument to
drm_simple_display_pipe_init(), which does not modify it. Hence make it
constant to protect it from unintended modification.
Issue found with Coccinelle.

Split out to make the functional changes stick out more.
All places where DRIVER_PRIME was used have been removed in previous
patches already.
v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.
v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.
v4: Don't add a space in i915_drv.c (Sam)
v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).
v6: Fixupe ingenic (new driver) while applying.

The GFX IP is inside of the ASPEED BMC SoC so there is little use
enabling it on a kernel that does not support ASPEED.
When building with COMPILE_TEST the architecture many not have CMA
support, so to avoid breaking the build we only select these options if
the architecture supports the contiguous allocator.
I suspect the DRM_PANEL came from a cut/paste error.

This driver is for the ASPEED BMC SoC's GFX display hardware. This
driver runs on the ARM based BMC systems, unlike the ast driver which
runs on a host CPU and is is for a PCI graphics device.
