x86/mce: Allow for copy_mc_fragile symbol checksum to be generated

commit b3149ffcdb31a8eb854cc442a389ae0b539bf28a upstream.

Add asm/mce.h to asm/asm-prototypes.h so that that asm symbol's checksum
can be generated in order to support CONFIG_MODVERSIONS with it and fix:

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

For reference see:

  4efca4ed05cb ("kbuild: modversions for EXPORT_SYMBOL() for asm")
  334bb7738764 ("x86/kbuild: enable modversions for symbols exported from asm")
