MIPS: Fix modversioning of _mcount symbol
In commit 827456e71036 ("MIPS: Export _mcount alongside its definition") the EXPORT_SYMBOL macro exporting _mcount was moved from C code into assembly. Unlike C, exported assembly symbols need to have a function prototype in asm/asm-prototypes.h for modversions to work properly. Without this, modpost prints out this warning: WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned. Fix by including asm/ftrace.h (where _mcount is declared) in asm/asm-prototypes.h.
