drm/exynos: Disable unused crtc planes from crtc
This patch moves the code which disables unused crtc planes from the
encoder to the crtc. Since there is a 1:1 encoder/crtc mapping in
exynos, the only valid crtc change the pre-existing code could catch is
disconnecting an active crtc from the encoder. Thus it is functionally
equivalent to just disable all planes attached to a crtc when the crtc
is disabled.
