Use dev_err_probe() helper function to handle probe deferral. It removes the open coded test for -EPROBE_DEFER but more importantly, it sets the deferral reason in debugfs which is great for debugging.

A minor thing, but dev_err_probe returns its err argument, so this construct can be written more tersely as:
return dev_err_probe(dev, PTR_ERR(aio->pclk), "Can't get the aio pclk\n");
and that also seems to be in common usage when browsing existing code.
