[PATCH] skfp warning fixes

drivers/net/skfp/fplustm.c: In function `enable_formac':
drivers/net/skfp/fplustm.c:552: warning: large integer implicitly truncated to unsigned type
drivers/net/skfp/fplustm.c:555: warning: large integer implicitly truncated to unsigned type

These arguments were changed to `const', so the compiler can now see that it's
doing and outw(..., 0xffffnnnn).  Cast the arg to ushort.
