Subject: drm/todo: Convert drivers to generic fbdev emulation

Git-commit: 80ae0369d3e4b8559c04e2b4de2b86640908f2fd
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
This replaces the original TODO item for drm_fb_helper_fbdev_setup()
and _teardown(), which are deprecated.
v2:
* remove driver-specific comments
* list some basic requirements
* keep a TODO item on drm_fb_helper_init()

-Most drivers can use drm_fb_helper_fbdev_setup() except maybe:
-
-- amdgpu which has special logic to decide whether to call
- drm_helper_disable_unused_functions()
-
-- armada which isn't atomic and doesn't call
- drm_helper_disable_unused_functions()
-
-- i915 which calls drm_fb_helper_initial_config() in a worker
-
-Drivers that use drm_framebuffer_remove() to clean up the fbdev framebuffer can
-probably use drm_fb_helper_fbdev_teardown().
+Most drivers can use drm_fbdev_generic_setup(). Driver have to implement
+atomic modesetting and GEM vmap support. Current generic fbdev emulation
+expects the framebuffer in system memory (or system-like memory).
