rtw89: debug: add stations entry to show ID assignment 



In order to trace the relation of IDs, we add this debugfs entry to make
them clear.

The output looks like:
  map:
          mac_id:    07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
          addr_cam:  07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
          bssid_cam: 01 00 00 00 00 00 00 00
          sec_cam:   00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
  VIF [0] 94:08:53:8e:ef:21
          bssid_cam_idx=0
          addr_cam_idx=0
          -> bssid_cam_idx=0
          sec_cam_bitmap=00 00 00 00 00 00 00 00
  STA [1] 58:00:e3:bb:9c:4f
          addr_cam_idx=1
          -> bssid_cam_idx=0
          sec_cam_bitmap=00 00 00 00 00 00 00 00
  STA [2] 94:08:53:8e:ef:75
          addr_cam_idx=2
          -> bssid_cam_idx=0
          sec_cam_bitmap=00 00 00 00 00 00 00 00
