Subject: [PATCH v2] Bluetooth: btnxpuart: Enable status prints for firmware download

This enables prints for firmware download which can help automation
tests to verify firmware download functionality.

A new flag BTNXPUART_FW_DOWNLOAD_ABORT is added which handles the
situation where driver is removed while firmware download is in
progress.
