[ Upstream commit 8e3709d7e3a67e2d3f42bd1fc2052353a5678944 ]
When building arm32 allmodconfig:
ld.lld: error: undefined symbol: ap_cp_unique_name
referenced by ap-cpu-clk.c clk/mvebu/ap-cpu-clk.o:(ap_cpu_clock_probe) in archive drivers/built-in.a
ap_cp_unique_name is only compiled into the kernel image when CONFIG_ARMADA_AP_CP_HELPER is selected (as it is not user selectable). However, CONFIG_ARMADA_AP_CPU_CLK does not select it.
This has been a problem since the driver was added to the kernel but it was not built before commit c318ea261749 ("cpufreq: ap806: fix cpufreq driver needs ap cpu clk") so it was never noticed.
