staging: rtl8723bs: add get_channel cfg80211 implementation

Browse source 
add get_channel cfg80211 implementation to let userspace
programs rely on nl80211 protocol to display channel
information.

Old iw dev output:

phy#0
	Interface wlan0
		ifindex 2
		wdev 0x1
		addr 34:c3:d2:73:eb:c7
		ssid Fabio
		type managed
		txpower 12.00 dBm

Fixed output:

phy#0
	Interface wlan0
		ifindex 2
		wdev 0x1
		addr 34:c3:d2:73:eb:c7
		ssid Fabio
		type managed
	new-->	channel 11 (2462 MHz), width: 20 MHz, center1: 2462 Mhz
		txpower 12.00 dBm
