Thanks for the report. This is clearly my fault for not testing the last
minute patch.
I have now replaced it with the one below and tested that it works
as intended.

    clk: make CONFIG_COMMON_CLK invisible
    
    All platforms that use the common clk infrastructure should select
    COMMON_CLK from platform code, and on all other platforms, it must
    not be enabled, so there is no point making the option visible to
    users, and when it is visible, we break randconfig builds.
