rtc: Remove wrong deprecation comment (2017-07-12 23:11:23 +0200)

----------------------------------------------------------------
RTC for 4.13

Subsystem:
- expose non volatile RAM using nvmem instead of open coding in many
drivers. Unfortunately, this option has to be enabled by default to not
break existing users.
- rtctest can now test for cutoff dates, showing when an RTC will start
failing to properly save time and date.
- new RTC registration functions to remove race conditions in drivers

Newly supported RTCs:
- Broadcom STB wake-timer
- Epson RX8130CE
- Maxim IC DS1308
- STMicroelectronics STM32H7

Drivers:
- ds1307: use regmap, use nvmem, more cleanups
- ds3232: temperature reading support
- gemini: renamed to ftrtc010
- m41t80: use CCF to expose the clock
- rv8803: use nvmem
- s3c: many cleanups
- st-lpc: fix y2106 bug
