Vincenzo Frascino 6be2a81ae4 clock_control: Add Beetle clock_control
This patch adds the clock_control implementation for the ARM LTD
Beetle platform.

The main features enabled are:
* Clock on and off in ACTIVE, SLEEP and DEEPSLEEP mode.
* PLL support (freq: 12, 36, 48 Mhz).

The integration with the existing drivers will be done in future
patches.
