[PATCH] drivers/net/smc-mca.c: cleanups

  
  This patch contains the following cleanups:
  - make a needlessly global function static
  - make three needlessly global structs static const
  
  Since after moving the now-static stucts to smc-mca.c the file smc-mca.h
  was empty except for two #define's, I've also killed the rest of
  smc-mca.h .
