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.

You added it in the prior patch, was that supposed to be done here? Kind 
of strange for h/w to optionally have a power-domain... It either has 
one or it doesn't. OTOH, making required is an ABI break.

This is vendor design. In old SoC's power domain for crypto HW
was not configurable, but in A1-series it is configurable.
