For newer SoCs csiphyX turns out to be a clock you really need to set. On sc8280xp for example we will encounter difficult to track down and root-cause RX CRC errors without setting the csiX_phy clock. On sdm845 and sm8250 we declare the csiXphy clock but seem to get away with not setting it. The right approach here is to set the clock when it is declared. If a SoC doesn't require or a SoC driver implementer doesn't think we need, then the clock ought to simply be omitted from the clock list. Include csiphyX in the set of permissible strings which will subsequently lead to the csiphyX clock being set during csiphy_set_clock_rates() phase.
