[PATCH] powerpc/xive: Properly use static keyword for inline function

[Mathieu Malaterre]

Fix fatal warning during compilation:

In file included from arch/powerpc/xmon/xmon.c:54:0:
./arch/powerpc/include/asm/xive.h:157:20: error: no previous prototype for âxive_smp_prepare_cpuâ [-Werror=missing-prototypes]
 extern inline int  xive_smp_prepare_cpu(unsigned int cpu) { return -EINVAL; }
                    ^
