      alpha: Reorganize rtc handling · 85d0b3a5

      Discontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem.
      
      The marvel platform requires that the rtc only be touched from the
      boot cpu.  This had been partially implemented with hooks for
      get/set_rtc_time, but read/update_persistent_clock were not handled.
      Move the hooks from the machine_vec to a special rtc_class_ops struct.
      
      We had read_persistent_clock managing the epoch against which the
      rtc hw is based, but this didn't apply to get_rtc_time or set_rtc_time.
      This resulted in incorrect values when hwclock(8) gets involved.
      
      Allow the epoch to be set from the kernel command-line, overriding
      the autodetection, which is doomed to fail in 2020.  Further, by
      implementing the rtc ioctl function, we can expose this epoch to
      userland.
      
      Elide the alarm functions that RTC_DRV_CMOS implements.  This was
      highly questionable on Alpha, since the interrupt is used by the
      system timer.
