i2c: Deprecate legacy RTC drivers 



We have a new RTC subsystem with better drivers.

Legacy driver status:
* ds1337: The DS1337 and DS1339 are now supported by the rtc-ds1307
  driver, so it looks to me like we could even delete the ds1337
  driver right away.
* ds1374: Will soon be replaced with Scott Wood's rtc-ds1374 driver.
* m41t00: The M41T00 is supported by the rtc-ds1307 driver. For the
  M41T81 and M41T85, the rtc-m41t80 driver written by Atsushi Nemoto
  should work.
