CONFIG_MVEBU_CLK_CPU is selected by ARMADA_370_CLK and ARMADA_XP_CLK, which themselves are selected by MACH_ARMADA_370 and MACH_ARMADA_XP respectively. So unless I'm missing something, this code is definitely reachable and compiled. You can use the mvebu_v7_defconfig of ARM32, and the code will be built.
