staging: brcm80211: remove custom string library again

There was a clean up commit for softmac driver. Do the same for fullmac
implementation.

Here:
 - strtoul and bcm_strtoul are changed to simple_strtoul
 - bcmstrtok -> strsep

All unused functions are deleted.

-/****************************************************************************
-* Function:   bcmstrtok
-*
-* Purpose:
-*  Tokenizes a string. This function is conceptually similiar to ANSI C strtok(),
-*  but allows strToken() to be used by different strings or callers at the same
-*  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.
