Subject: [PATCH v4 01/20] dt-bindings: arm: cpus: Add Apple A7-A11 CPU cores

Add the following CPU cores:

- apple,cyclone: A7 cores
- apple,typhoon: A8 cores
- apple,twister: A9 cores
- apple,hurricane-zephyr: A10 logical cores
- apple,monsoon: A11 performance cores
- apple,mistral: A11 efficiency cores

In the Apple A10, there are physical performance-efficiency cores that
forms logical cores to software depending on the current p-state, and
only one type of core may be active at one time.

This follows the existing newest-first order.
