[PATCH REPOST] pcmcia: Remove NEC VRC4173 CARDU

[Sebastian Andrzej Siewior]

This driver is the very definition of bitrotting:
- Introduced in commit
  79a140932c776 ("[PATCH] mips: vR41xx updates")
  which is 2.6.11-rc3.

- Provides ->register_callback which was removed in commit
  7f316b033b36a ("[PATCH] pcmcia: remove socket register_callback")
  which is v2.6.14-rc3

- Uses INIT_WORK() with three arguments which was removed in commit
  65f27f38446e1 ("WorkStruct: Pass the work_struct pointer instead of context data")
  which is v2.6.20-rc1

- Provides ->inquire_socket and uses socket_cap_t which was removed in
  commit
  b7949fdacbe00 ("[PCMCIA] Remove inquire_socket")
  which is 2.5.72

- Provides ->get_io_map which was removed in commit
  d7de1b64a23b9 ("[PCMCIA] pcmcia-2: Remove get_io_map and get_mem_map socket methods.")
  which is 2.5.66

Remove VRC4173 CARDU from the tree because it never had the luck to be
successfully compiled. Let it finally find peace in byte heaven.
