MIPS: Export {copy, clear}_page functions alongside their definitions

Browse source 
Now that EXPORT_SYMBOL can be used from assembly source, move the
EXPORT_SYMBOL invocations for the copy_page & clear_page functions to be
alongside their definitions.

With this change there are no longer any symbols exported from
mips_ksyms.c so remove the file.
