drm/exynos: Fix FIMD buffer size calculation
Commit adacb228d72b ("drm: Exynos: Respect framebuffer pitch for
FIMD/Mixer") fixed the buffer size calculation by using the FB
pitch value but later commit 26b9c2813ede1 ("drm/exynos: remove
struct *_win_data abstraction on planes") added a regression so
fix the buffer size calculation again.
Tested on Chromebook Snow / Peach Pit.
Fixes: 26b9c2813ede1 ("drm/exynos: remove struct *_win_data abstraction on planes")
