devm_clk_get()?
Don't mix devm and non-devm functions like this, all devm functions
should be placed first.

Your binding has reset-names defined, please request reset controls by
name. Use devm_reset_control_get_explicit() instead, same below.

These could return -EPROBE_DEFER, I suggest to
return dev_err_probe(&pdev->dev, PTR_ERR(cru->cmn_restb),
"failed to get cpg cmn_restb\n");
instead, same below.
