arm: mvebu: move SYS_MVEBU_PLL_CLOCK to Kconfig

The main PLL frequency is 2GHz for Armada-XP and 1GHZ for Armada 375, 38x and 39x.

I've set the value for ARMADA_3700 and ARMADA_8K to 2GHz. I'm not sure if this is correct but it is the same value that these SoCs would have had when the value was defined in soc.h.
