[PATCH V2 5/9] sunxi: H616: dram: Update mbus priorities

From: Jernej Skrabec <jernej.skrabec at gmail.com>

CSI1 channel (22) is missing and IOMMU (25) has priority flag set in
vendor bootloader. Fix that.

While at it, replace bandwidth flag with priority since original flag has
always value "true".
