[PATCH v2 1/2] media: dt-bindings: allwinner: video-engine: Fix number of IOMMU channels

[Jernej Skrabec <jernej.skrabec@xxxxxxxxx>]

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")
