arm: dts: lpc32xx: add clock controller device node
NXP LPC32xx SoC has a clocking and power control unit (CPC) as a part of system control block (SCB). CPC is supplied by two external oscillators and it manages core and most of peripheral clocks, the change adds SCB and CPC descriptions to shared LPC32xx dtsi file.
