    LinuxKPI: extract stringify() in their own header file
    
    Add linux/stringify.h as directly included by drivers.  Remove the
    definitions from compiler.h and include the new header in places
    where the stringify macros are already used without linuxkpi.
    
    I have adjusted the Copyright of the new file according to the commit
    originaly adding the macros (99e690772adbcb78c9e8441bedcf1913d72ea72f).
