The DCP block is present on 6sll and 6ull but not enabled. The hardware is
mostly compatible with 6sl, the only important difference is that explicit
clock enabling is required.
There were several issues with the functionality of this driver (it didn't
even probe properly) but they are fixed in cryptodev/master by this series:

Changes since v1:
* Add devicetree maintainers for dt-bindings
* Add a patch enabling in imx_v6_v7_defconfig. Since tcrypt now passes this
shouldn't cause any issues
* Link to v1: https://lore.kernel.org/patchwork/cover/994893/
