It is nowhere used in the kernel. It also seems to be lacking the
proper fiber advertise flags. Remove it.

Maybe also remove the #define for PHY_BCM_FLAGS_MODE_1000BX? Maybe
there is an out of tree driver using this? By removing the #define, it
will fail at compile time, making it obvious the support has been
removed?
Otherwise:

AFAICS this flag is still used in BCM54616S PHY driver code.
