staging: brcm80211: remove duplicated file, bcmutils.c

Remove duplicated file, bcmutils.c under brcm80211/brcmfmac.
brcm80211/util/bcmutils.c will be shared between softmac
& fullmac. Makefile, and some other files are also modified
accordingly

+*  time. Each call modifies '*string' by substituting a NULL character for the
+*  first delimiter that is encountered, and updates 'string' to point to the char
+*  after the delimiter. Leading delimiters are skipped.
+*
+* Parameters:
+*  string      (mod) Ptr to string ptr, updated by token.
+*  delimiters  (in)  Set of delimiter characters.
+*  tokdelim    (out) Character that delimits the returned token. (May
+*                    be set to NULL if token delimiter is not required).
+*
+* Returns:  Pointer to the next token found. NULL when no more tokens are found.
