[Bluetooth] Add UART driver for Texas Instruments' BRF63xx chips

Browse Source 
Add support for Texas Instruments' HCI Low Level (HCILL) Bluetooth
protocol, which is a power management extension to H4. The HCILL is
widely used by TI's BRF63xx Bluetooth chips.

HCILL (HCI Low Level) is a serial protocol for communication
between Bluetooth device and host. This protocol is required for
serial Bluetooth devices that are based on Texas Instruments'
BRF chips.
Say Y here to compile support for HCILL protocol.
