[PATCH 2/3] drm/rcar: Only update planes on active crtc

[Daniel Vetter]

R-car does runtime pm (that's why it's committing plane state only at
the end). Therefore better to only update planes on active crtc. Note
that since the helpers always add all enabled planes when doing a
modeset change on a crtc we are guaranteed to update plane hw state to
the latest requested state each time the crtc is enabled.
