rtc: s5m: consolidate two device type switch statements
In probe the configuration of driver for different chipsets was done in two switch (pdata->device_type) statements. Consolidate them into one switch statement to increase code readability. Additionally check the return value of regmap_irq_get_virq and exit probe on error.
