The devicetree bindings for this driver specify that the two allowed
clock names are io and core. Change this driver to look for io, but
allow any name if it fails for backwards compatibility. Follow the same
pattern used in sdhci-pxav3.

It is nicer to handle EPROBE_DEFER e.g.

	if (IS_ERR(clk) && PTR_ERR(clk) != -EPROBE_DEFER)
		clk = devm_clk_get(dev, NULL);
	if (IS_ERR(clk)) {
		ret = PTR_ERR(clk);
		dev_err_probe(dev, ret, "failed to get io clock\n");
