If DRM_FBDEV_EMULATION is not selected in the config then we should not
setup a framebuffer console.

It should just magically work, and this patch here just removes a bit more
dead code in the rockchip driver itself that's not needed in case fbdev
emulation is disabled.
Can you please double-check this is the case and then resend with a
clarified commit message?
Thanks, Daniel

If DRM_FBDEV_EMULATION is not selected in the config then we can save a
bit of space by not including the framebuffer code.

You're right, it does work without this change, so this is just to save
a bit of space when we don't need this feature.
v2:
- change commit message to clarify that this is only to remove some dead
code
