[PATCH v4 13/14] wifi: rtlwifi: Add rtl8192du/sw.{c,h}

[Bitterblue Smith <rtl8821cerfe2@gmail.com>]

These contain the new module's entry point.

Signed-off-by: Bitterblue Smith <rtl8821cerfe2@gmail.com>
---
v4:
 - Delete unnecessary out of memory message.
 - Constify rtl8192du_hal_ops, rtl92du_interface_cfg, rtl92du_hal_cfg.
   (rtl92du_mod_params can't be const because module_param_named()
   doesn't accept it.)
 - Move MODULE_* to the bottom of sw.c.
 - Delete sw.h and the global mutexes. The mutexes were moved to
   struct rtl_priv. sw.h is unnecessary now.
 - Add functions to initialise and free the formerly global variables:
	curveindex_2g
	curveindex_5g
	mutex_for_hw_init
	mutex_for_power_on_off

v3:
 - Add USB ID 2001:330c found by Zenm Chen.

v2:
 - Patch is new in v2, split from patch 3/3 in v1.
