ARM: versatile: Don't use platform clock for Integrator & VE

Due to automatic merge of a613163dff
"ARM: integrator: convert to common clock" and
56a34b03ff "ARM: versatile: Make
plat-versatile clock optional" two platforms: Integrator and
Versatile Express now select both COMMON_CLK and
PLAT_VERSATILE_CLOCK which breaks building them. Fixed now.
