Add ieee80211_rx_check_bss_color_collision routine in order to introduce BSS color collision detection in mac80211 if it is not supported in HW/FW (e.g. for mt7915 chipset). Add IEEE80211_HW_DETECTS_COLOR_COLLISION flag to let the driver notify BSS color collision detection is supported in HW/FW. Set this for ath11k which apparently didn't need this code.
