ARM: dts: wpcm450: Add clock controller node

Browse Source 
This declares the clock controller and the necessary 48 Mhz reference
clock in the WPCM450 device. Switching devices over to the clock
controller is intentionally done in a separate patch to give time for
the clock controller driver to land.
