- AVRCP Controller: Added send generic PASS THROUGH command
- HID Host: storage for HID Descriptors is now optional
- HCI: support newer AIROC Controller that require Download Mode with ENABLE_AIROC_DOWNLOAD_MODE
- Zephyr: provide hal_flash_bank implementation for native flash driver
### Fixed
- GAP: store link key for standard/non-SSP pairing
- BENP: emit channel opened with ERROR_CODE_REMOTE_USER_TERMINATED_CONNECTION if connection cannot be set up
