ARM: dts: lpc32xx: Use syscon for system control block

Browse Source 
The clock controller is a part of NXP LPC32xx system control block (SCB),
and SCB provides a number of controllers apart of the clock controller.

[vzapolskiy]:
1. kept a simple comment,
2. renamed SoC specific compatible to 'nxp,lpc3220-scb' due to the SoC UM,
3. changed size in 'ranges', since it should cover more SCB functions,
4. updated the commit message.
