spmi: pmic-arb: Replace three IS_ERR() calls by null pointer checks in spmi_pmic_arb_probe()
The devm_ioremap() function does not return error pointers. It returns NULL on error. This issue was detected once more also by using the Coccinelle software. Update three checks (and corresponding error codes) for failed function calls accordingly.
