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.
