rtl8723{bc}s is WiFi/Bluetooth module, WiFi part is connected over SDIO
while bluetooth is connected over UART.

This series adds support for rtl8723bs/rtl8723cs bluetooth.

Bluetooth module in rtl8723cs is buggy - it advertises some features that
it doesn't support and responds either with garbage or with errors on
corresponding commands. Unfortunately that confuses bluetooth stack,
so we need to introduce another quirk.

Patches for Pine64 and Sopine are provided as examples since WiFi/BT module
is optional on these boards.
