bluetooth: harden interactive controller power handling - #560
Merged

Conversation
BlueZ on Debian and Ubuntu can ignore or defer power requests when bluetoothctl is driven through a plain stdin pipe, even though the same command succeeds in a manual terminal session. Use an expect PTY when available, wait for the BlueZ acknowledgement, and require a stable Powered state before declaring success. Prepare rfkill and expect through the package provider on Debian-family images, and use the PTY scanner as the first scan fallback. Keep the established default-controller and non-PTY fallbacks for Yocto and minimal images. Signed-off-by: Srikanth Muppandam <smuppand@qti.qualcomm.com>
