Bluetooth: hciuart: Add support QCA chipset for UART

Browse Source 
QCA61x4 chips have supported sleep feature using In-Band-Sleep commands
to enable sleep feature based on H4 protocol. After sending
patch/nvm configuration is done, IBS mode will be up and running

The Qualcomm Atheros protocol supports HCI In-Band Sleep feature
over serial port interface(H4) between controller and host.
This protocol is required for UART clock control for QCA Bluetooth
devices.
