hw/sparc: Allow building without the leon3 machine

When building without the leon3 machine, we get this link failure:

  /usr/bin/ld: target_sparc_int32_helper.c.o: in function `leon3_irq_manager':
  target/sparc/int32_helper.c:172: undefined reference to `leon3_irq_ack'

This is because the leon3_irq_ack() is declared in hw/sparc/leon3.c,
which is only build when CONFIG_LEON3 is selected.

Fix by moving the leon3_cache_control_int() / leon3_irq_manager()
(which are specific to the leon3 machine) to hw/sparc/leon3.c.
Move the trace events along (but don't rename them).

leon3_irq_ack() is now locally used, declare it static to reduce
its scope.
