sparc: Fix CPU counter support
The SPARC processors supported by RTEMS have no built-in CPU counter
support. We have to use some hardware counter module for this purpose.
The BSP must provide a 32-bit register which contains the current CPU
counter value and a function for the difference calculation. It can use
for example the GPTIMER instance used for the clock driver.
