Subject: [PATCH v8 19/23] dt-bindings: crypto: meson: support new SoC's

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.
