Respect DRM's kconfig setting for fbdev console emulation. If enabled,
it will select all required config options. So remove them from vmwgfx's
Kconfig file.

This changes the behavior a bit, I guess DRM_VMWGFX (or at least DRM_VMWGFX_FBCON) would need to select DRM_FBDEV_EMULATION to preserve the old behavior, but that's largely due to the fact that given how those options were setup we never run without FB set. In general it should be ok and looks more reasonable than the current setup. I'll try it out on Monday just in case, but for now:
