powerpc/xmon: Fix build failure for 8xx

Browse Source 
[ Upstream commit f3e9040801 ]

With CONFIG_PPC_8xx and CONFIG_XMON set, kernel build fails with

  arch/powerpc/xmon/xmon.c:1379:12: error: 'find_free_data_bpt' defined
  but not used [-Werror=unused-function]

Fix it by enclosing find_free_data_bpt() inside #ifndef CONFIG_PPC_8xx.
