rtc: rzn1: Check return value in rzn1_rtc_probe 

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2183349

    rtc: rzn1: Check return value in rzn1_rtc_probe

    The rzn1_rtc_probe() function utilizes devm_pm_runtime_enable()
    but wasn't checking the return value. Fix it by adding missing
    check.
