staging: dgnc: removes proc code

This patch removes the dgnc_proc.c and dgnc_proc.h files and all
references to proc functions in dgnc_driver.c. This also removes proc.h
from the include headers in driver.c, mgmt.c and sysfs.c and proc.o
from the Makefile.

Drivers now use sysfs instead of proc.

- *  Description:
- *
- *     Describes the private structures used to manipulate the "special"
- *     proc constructs (not read-only) used by the Digi Neo software.
- *     The concept is borrowed heavily from the "sysctl" interface of
- *     the kernel.  I decided not to use the structures and functions
- *     provided by the kernel for two reasons:
- *
- *       1. Due to the planned use of "/proc" in the Neo driver, many
- *          of the functions of the "sysctl" interface would go unused.
- *          A simpler interface will be easier to maintain.
- *
- *       2. I'd rather divorce our "added package" from the kernel internals.
- *          If the "sysctl" structures should change, I will be insulated
- *          from those changes.  These "/proc" entries won't be under the
- *          "sys" tree anyway, so there is no need to maintain a strict
- *          dependence relationship.

- *  Each entry in a DGNC proc directory is described with a

- *  as a table.  All "tables" are terminated by an entry with

- *

- *    const char *name       -- ASCII name associated with the /proc entry.
- *
- *    mode_t mode            -- File access permisssions for the /proc entry.
- *
- *    dgnc_proc_entry *child -- When set, this entry refers to a directory,
- *                              and points to the table which describes the
- *                              entries in the subdirectory
- *
- *    dgnc_proc_handler *open_handler -- When set, points to the fxn which
- *                                       does any "extra" open stuff.
- *
- *    dgnc_proc_handler *close_handler -- When set, points to the fxn which
- *                                        does any "extra" close stuff.
- *
- *    dgnc_proc_handler *read_handler -- When set, points to the fxn which
- *                                       handle outbound data flow
- *

- *                                        handles inbound data flow
