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.

Instead of blind copy of nsim_em.dts re-structure this way:
* nsim.dtsi - Top-level "board" description re-usable for
| all nSIM-based "boards".
|
| Even though it's not needed right now but it
| allows to add other ARC core families in the future.
|
\_ nsim_em.dtsi - Common definitions for boards with ARC EM cores
|
\_ Real boards with ARC EM cores
