Subject: [PATCH v9 8/9] Bluetooth: btintel: Collect tlv based active firmware build info in FW mode

From: Lokendra Singh <lokendra.singh@intel.com>

In Operational firmware mode, 'Minimum FW version' TLV ID is not available.
So, we cannot fetch already running firmware info for comparison against
another build. However, It can be collected using a combination of other
TLV ID's information.
