drm/exynos: Fix FIMD buffer size calculation

Browse Source 
Commit adacb228d7 ("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")
