ARM: 6278/2: fix regression in RealView after the introduction of pclk

The patch to add the apb_pclk to the AMBA/PrimeCell bus broke
RealView, since the clockdevice is not registered at probe() time.
This moves clock initialization to a core_initcall()

[rmk:moved before the problematical commit to avoid bisect problems]
