deepin: config: remove R8712U

deepin inclusion
category: other

Per commit commit 41e883c upstream.

This driver is in the staging area since 2010.

The following reasons lead to the removal:
- This driver generates maintenance workload for itself and for API wext
- A MAC80211 driver was available in 2016 time frame; This driver does
  not compile anymore but would be a better starting point than the
  current driver. Here the note from the TODO file:
  A replacement for this driver with MAC80211 support is available
  at https://github.com/chunkeey/rtl8192su
- no progress changing to mac80211
- Using this hardware is security wise not state of the art as WPA3 is
  not supported.
