Matija Glavinic Pecotic b4210b10dc x86/rtc: Remove __init for runtime functions

[ Upstream commit 775d3c514c5b2763a50ab7839026d7561795924d ]

set_rtc_noop(), get_rtc_noop() are after booting, therefore their __init
annotation is wrong.

A crash was observed on an x86 platform where CMOS RTC is unused and
disabled via device tree. set_rtc_noop() was invoked from ntp:
sync_hw_clock(), although CONFIG_RTC_SYSTOHC=n, however sync_cmos_clock()
doesn't honour that.

  Workqueue: events_power_efficient sync_hw_clock
  RIP: 0010:set_rtc_noop
  Call Trace:
   update_persistent_clock64
   sync_hw_clock

Fix this by dropping the __init annotation from set/get_rtc_noop().
