Update clk_composite_set_parent() to use -ENOSYS, which is the correct error code for U-Boot. Also rearrange the code so that the error condition is clearly indicated and the function runs to the end in the normal case, since this is the common style in U-Boot.

Will this be applied to the whole clock subsystem? From what I can tell, the clock subsystem returns ENOSYS in these situations, and drivers return ENOTSUPP. It would be great if we could unified all these so callers could check for one return value.
