Move the plane clip rectangle handling into
drm_atomic_helper_check_plane_state(). Drivers no longer
have to worry about such mundane details.
v2: Convert armada, rcar, and sun4i as well
v3: Resolve simple_kms_helper conflict

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.
Note that this replaces crtc_state->adjusted_mode usage with
crtc_state->mode. The latter is the correct choice since that's the
mode the user provided and it matches the plane crtc coordinates
the user also provided.
Once everyone agrees on this we can move the clip handling into
drm_atomic_helper_check_plane_state().

min_scale and max_scale in sun8i_vi_layer_atomic_check() can be used
without initialization.
Fix that.

Now that we have all required bits, add support for YUV formats.
DRM subsystem doesn't know YUV411 semi-planar format, so leave that out
for now.

Basic principle of operation when using YUV framebuffer is that chroma
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.

This commit expands translation of DRM YUV format to HW specific
information.
It doesn't do any functional changes.

This commit adds basic support for VI planes. They are meant for video
overlay and because of that they support YUV formats too. However, using
YUV format is not straightforward, so only RGB formats are supported for
now.
