RKI Build Error - rtems_clock_get not available on 4.12

[Pavel Pisa]

Hello Habeeb,

rtems_clock_get() has been obsoleted long time ago
and has been removed in

    e65c45c4b6cf6dfb485bef48385e39969de8b361
    Obsolete rtems_clock_get() directive.

    This service was marked as deprecated long prior to the 4.11 release
    series and is now being removed.
    
    closes #2676.
    

You should rewrite code as

   rtems_interval ticks;
-  rtems_clock_get(RTEMS_CLOCK_GET_TICKS_SINCE_BOOT,&ticks);
+  ticks = rtems_clock_get_ticks_since_boot();


If you need to be compatible even with very old RTEMS versions, probably
pre-4.9, you can use

   rtems_interval ticks;
  #ifndef RTEMS_CLOCK_GET_TICKS_SINCE_BOOT
   ticks = rtems_clock_get_ticks_since_boot();
  #else /*RTEMS_CLOCK_GET_TICKS_SINCE_BOOT*/
   rtems_clock_get(RTEMS_CLOCK_GET_TICKS_SINCE_BOOT,&ticks);
  #endif /*RTEMS_CLOCK_GET_TICKS_SINCE_BOOT*/
 
Best wishes,

               Pavel
