drivers: net: wireless: add HTC's bcmdhd_4335_mcc

From m7stockui-3.4.10-gef77362.

Modifications from stock HTC driver:
* Remove poorly commented-out CFLAGS section from Makefile
* Make CONFIG_BCMDHD_4335_MCC select WIRELESS_EXT, WEXT_PRIV
* Fix msm_watchdog.h include in dhd_sdio.c
* Our kernel does not need OLD_CFG_80211; removing this flag also
  required the following fixes in wl_cfg80211.c
  - L292: ifdef out used_default_ssid
  - L6698-6702: ifdef out usage of wl_cfg80211_hostapd_sec()

Changes outside of driver: Make necessary additions (and block with
CONFIG_BCMDHD_4335_MCC where appropriate) in:
* drivers/mmc/host/msm_sdcc.c
* include/linux/ieee80211.h
* include/linux/nl80211.h
* include/linux/wlan_plat.h
