crypto: talitos - Add a feature to tag SEC1
We add a new feature in the features field, to mark compatible "fsl,sec1.0" We also define a helper function called has_ftr_sec1() to help functions quickly determine if they are running on SEC1 or SEC2+. When only SEC1 or SEC2 is compiled in, has_ftr_sec1() return trivial corresponding value. If both are compiled in, feature field is checked.
