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.

dts: Replace status = "ok" with status = "okay" The DT spec. only has "okay" and not "ok". The Linux kernel has around 12k "okay"s and 300 "ok"s. The scripts/dts scripts only check for "disabled", so should be safe re. those at least. The replacement was done with git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>
