staging: rtl8192e: Remove dead code: rtl_dm.[ch]

Browse source 
- Remove unused fields in dig_t structures. Some of them were only
  initialized and never accessed.
- Remove unused enums/macros/defines in rtl_dm.h
- Remove duplicated function declarations
- Remove unused dm_change_dynamic_initgain_thresh() function
- Remove unused dm_shadow_init() function
