Subject: [PATCH 1/2] media: dt-bindings: allwinner: video-engine: Fix number of IOMMU channels

Cedrus (video engine) on Allwinner H6 actually uses two IOMMU channel,
not just one. However, Cedrus on SoCs like D1 only uses one channel.

Allow up to 2 IOMMU channels.

Fixes: 62a8ccf3a248 ("arm64: dts: allwinner: h6: Fix Cedrus IOMMU usage")
