dt-bindings: crypto: fsl-dcp: add imx6sl and imx6ull compatible

Currently the dtbs_check for imx6 generates warnings like this:

'fsl,imx6sl-dcp' is not one of ['fsl,imx23-dcp', 'fsl,imx28-dcp']
['fsl,imx6sl-dcp', 'fsl,imx28-dcp'] is too long

or

'fsl,imx6ull-dcp' is not one of ['fsl,imx23-dcp', 'fsl,imx28-dcp']
['fsl,imx6ull-dcp', 'fsl,imx28-dcp'] is too long

So add them to the devicetree binding.
