The bus clock is often named "apb_pclk", but it's too late to change
that now, and it's not clear if the device is actually on APB.

The problem with "sclk_adc" is that it's very close to the name used
in the clock provider, with is CLK_SCLK_TSADC. Please try to avoid
the ambiguity here and make it clear that they are not referring
to the same thing. "internal" or "special" might be good if you want
to avoid "sclk".
