Remove the apparently unreferenced include/linux/mtd/jedec.h header
file.

  is this header file being used these days?  because it keeps showing
up in my scan for unused header files, and i've submitted a patch to
delete it but ... there it is.

  can someone clarify this one way or the other?  thanks.
