Add the SDIO module for the RTL8723BS, the SDIO variant of the RTL8723B. It binds the Realtek SDIO device ids to the shared rtw88 SDIO probe and points it at the RTL8723B chip information. The device id table carries the same six ids the staging rtl8723bs driver binds to this chip, so the staging driver can be dropped without losing hardware support. I only have the 0xb723 variant to test with; the other five are included for parity with staging, which has carried them for years, rather than being left behind. The RTL8723B chip support is based on the initial work by Michael Straube [off-list ref].
