Now crypto module available at G12A/G12B/S4/A1/SM1/AXG. 1. Add new compatibles: - amlogic,g12a-crypto - amlogic,axg-crypto - amlogic,a1-crypto - amlogic,s4-crypto (uses a1-crypto as fallback) Difference between this compatibles: * Different registers offset and the number of setup descriptors. * GXL doesn't support hashing like the others. * G12A/B and A1/S4 crypto HW don't support 192 AES key. * GXL, G12A/B and AXG require a reverse IV key before processing. 2. Add power-domains in schema, which is required only for A1. This is specific vendor design: in old SoC's power domain for crypto HW was not configurable, but in A1-series it is configurable.
