[ Upstream commit f3e90408019b353fd1fcd338091fb8d3c4a1c1a5 ]

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.
