rtc: gemini: add return value validation
Function devm_ioremap() will return a NULL pointer if it fails to remap IO address, and its return value should be validated before it is used. However, in function gemini_rtc_probe(), its return value is not checked. This may result in bad memory access bugs on future access, e.g. calling the function gemini_rtc_read_time().
