Subject: [PATCH] Use hciattach tool for the RPI3 target

There is an UART HW differnece between RPI3 B and RPI3 B+
model such as cts pin setting. Because of this we should
use the different value for Uart Speed and flow control.
btattach tool operates the firmware download and Uart
setting in the kernel driver as the proto. So we can't
use the btattach tool for RPI3 target.
