Create the new compatibles to identify AST2600 MAC0/1 and MAC3/4.
Add conditional schema constraints for Aspeed AST2600 MAC controllers:
- For "aspeed,ast2600-mac01", require rx/tx-internal-delay-ps properties
  with 45ps step.
- For "aspeed,ast2600-mac23", require rx/tx-internal-delay-ps properties
  with 250ps step.

That difference does not justify different compatibles. Basically you
said they have same programming model, just different hardware
characteristics, so same compatible.
