d3820952ea drm/tinydrm: Use drm_fb_cma_fbdev_init_with_funcs/fini() 
Use drm_fb_cma_fbdev_init_with_funcs() and drm_fb_cma_fbdev_fini() which
relies on the fact that drm_device holds a pointer to the drm_fb_helper
structure. This means that the driver doesn't have to keep track of that.
Also use the drm_fb_helper functions directly.
Remove todo entry.

planes have to be upscaled to same size as luma.

Because of that, expand DE2 scaler library to support that.

BSP driver uses another set of FIR filter coefficients for YUV planes.

5bb5f5dafa drm/sun4i: Reorganize UI layer code in DE2 
Till now, DE2 driver supported only UI planes. Before we add support for
VI planes, lets split out UI layer specific code from common parts. This
commit does the following:
- renames sun8i_layer.c to sun8i_ui_layer.c
- moves UI channel specific code to sun8i_ui_layer.c
- moves common code from sun8i_layer.c to sun8i_mixer.c
- renames function and structure names so it is apparent where they
belong to

No functional change is made.

f356fe8e0f drm/sun4i: Start using layer id in DE2 driver 
Till now, plane selection was hardcoded to first overlay in first UI
channel and layer parameter is unused.

Rename and add parameters to layer functions so they would represent HW
more accurately and start using then.

It turns out that overlays don't fit well in current DRM design, because
they can't be blended together or scaled independetly when they are set
to same channel. Because of that, always use only first overlay in each
channel.
