iommu: sun50i: Add H616 compatible string
The IOMMU IP in the Allwinner H616 SoC is *almost* compatible to the H6,
but uses a different reset value for the bypass register, and adds some
more registers.
While a driver *can* be written to support both variants (which we in
fact do), the hardware itself is not fully compatible, so we require a
separate compatible string.
Add the new compatible string to the list, but without changing the
behaviour, since the driver already supports both variants.
