    rtc: log error message when driver initialisation fails

    doc: diagnose problem with RTC interrupts on Linux
    
    This commit updates the FAQ with a new entry.
    
    chronyd's Linux RTC driver (rtc_linux.c) requires the following ioctl
    requests to be functional:
    
      RTC_UIE_ON
      RTC_UIE_OFF
    
    However, a Linux system's RTC driver does not necessarily implement them,
    as noted in these previous commits:

      rtc: handle RTCs that don't support interrupts

      rtc: extend check for RTCs that don't support interrupts
      Thu Dec 12 12:50:19 2019 +0100
    
    Fortunately, the Linux kernel can be built with software emulation of
    these hardware requests, by enabling the following config variable:
    
      CONFIG_RTC_INTF_DEV_UIE_EMUL
        Provides an emulation for RTC_UIE if the underlying rtc chip
        driver does not expose RTC_UIE ioctls. Those requests generate
        once-per-second update interrupts, used for synchronization.
    
        The emulation code will read the time from the hardware
        clock several times per second, please enable this option
        only if you know that you really need it.
    
    This commit records these facts for the benefit of the user.
