Subject: [PATCH 5.10 47/98] drm/mediatek: Add AAL output size configuration

From: "jason-jh.lin" <jason-jh.lin@...iatek.com>

[ Upstream commit 71ac6f390f6a3017f58d05d677b961bb1f851338 ]

To avoid the output width and height is incorrect,
AAL_OUTPUT_SIZE configuration should be set.

Fixes: 0664d1392c26 ("drm/mediatek: Add AAL engine basic function")
