 Unfortunately, most SPARC SoCs supported by RTEMS lack a proper free-
 running counter. The only exception is the GR740. For the pre-qualified
 GR712RC BSP, the current implementation is too complicated. Make the fall
 back to a free-running GPTIMER mandatory for the leon3 BSP family to
 simplify things.
