Ben Young Tae Kim 83e81961ff Bluetooth: btqca: Introduce generic QCA ROME support
This is for supporting BT for QCA ROME with vendor specific
HCI commands and initialization on the chip. This will have
USB/UART implementation both, but for now, adding UART vendor
specific commands to patch downloading and set Bluetooth device
address using vendor specific command.
