Doesn't the following do just that?

clk = clk_register_fixed_rate(NULL, "apb_pclk", NULL, CLK_IS_ROOT,
                              126000000);

Anyway, with this patch, shouldn't we fix drivers/clk/clk-bcm2835.c not
to register clocks that match those that are added to DT in this patch?
Actually, to maintain DT ABI (new kernels working with old or new DT),
we probably need to keep the code in clk-bcm2835.c, but make it
conditional upon whether there's a clock node in the DT file.
