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.
