wpanusb: enhancement for beagleconnect freedom gateway

• get valid channels from device
• disable IEEE802154_HW_PROMISCUOUS mode to disable error is kernel logs
• with the changes Sub-G(with zephyr patch for PA) works without issues
• 2.4G fails at setting channel
• add simple rmmod script to remove assosciated modules, useful during driver testing
