Piotr Zięcik 7d56fc35fd dts: Add information about CPU frequency to the cpu nodes
This commit adds 'clock-frequency' property to the cpu nodes.
The clock frequency specified in the added property is used
during platform configuration. Examples:

- The SWO logger uses clock frequency to configure SWO output.
- Plenty of platforms need CPU clock specified for their HAL.
- Most of devices with USB needs information about CPU clock
  in order to configure USB clock source.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.

Getting Started
***************

Welcome to Zephyr! See the `Introduction to Zephyr`_ for a high-level overview,
and the documentation's `Getting Started Guide`_ to start developing.

Community Support
*****************

Community support is provided via mailing lists and Slack; see the Resources
below for details.
