Subject: [PATCH 5.4 084/214] gpu/drm: ingenic: Use the planes src_[x,y] to configure DMA length

From: Paul Cercueil <paul@...pouillou.net>

[ Upstream commit 52e4607dace1eeeb2e012fca291dc4e6cb449bff ]

Instead of obtaining the width/height of the framebuffer from the CRTC
state, obtain it from the current plane state.

v2: No change
