staging: rtl8723bs: rename enum items related to channel bonding

since rtl8723bs card allows only 20Mhz and 40Mhz channels,
rename enum items related to channel bonding accordingly to
the only composite channel bandwidth allowed in 2.4Ghz
(i.e. 40Mhz) in a HT context (since VHT isn't supported)

Example:

VHT_DATA_SC_20_LOWER_OF_80MHZ ->
HT_DATA_SC_LOWER_OF_40MHZ

staging: rtl8723bs: remove code related to unsupported channel bandwidth

remove all code related to unsupported channel
bandwidth (i.e. 80, 80+80, 160 Mhz). rtl8723bs NIC
works only on 20 and 40 Mhz channels.

Module parameter rtw_bw_mode can only have two
values: 0 and 1 (20 Mhz and 40Mhz). So modify
the default value setting to zero the 5Ghz nibble.

Comments modified accordingly.

staging: Add rtl8723bs sdio wifi driver

The rtl8723bs is found on quite a few systems used by Linux users,
such as on Atom systems (Intel Computestick and various other
Atom based devices) and on many (budget) ARM boards such as
the CHIP.

The plan moving forward with this is for the new clean,
written from scratch, rtl8xxxu driver to eventually gain
support for sdio devices. But there is no clear timeline
for that, so lets add this driver included in staging for now.
