Remove RTC register value checks from the rtc-ds1307 probe() function.
They were left over from the legacy style I2C driver, which had to defend
against finding a non-RTC chip when the driver was probed.
Also fix a minor glitch in the alarm support: DS1307 chips don't have
alarms, so name those methods after one of the chips which actually *do*
have alarms (DS1337).
