Subject: MIPS: Restore symbol versions for copy_page_cpu and clear_page_cpu

MIPS: Restore symbol versions for copy_page_cpu and clear_page_cpu

The mips build generates two warnings:

WARNING: modpost: EXPORT symbol "clear_page_cpu" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: modpost: EXPORT symbol "copy_page_cpu" [vmlinux] version generation failed, symbol will not be versioned.

Add their prototypes to be defined in asm-prototypes.h, so that
genksyms knows the types of these symbols and can generate CRCs for
them.
