linux-firmware: Fix USB disconnection issue in Intel BT 7265

This is firmware patch for INtel Bluetooth 7265 (StP D1)
StP D1 FW Patch Version: 0xFB

This patch contains the following fixes:
- Fix action map
- Event Buffer: having only one single command buffer
- Recover from HW error: watchdog issue will send Hw Error Event to host, and
  host will reset the host stack and the controller
- USB disconnection: (Tx/Rx buffer free): L1 vector is corrupted due to the FIQ
  lock and DMA transaction. The USB module is in the IRQ (L1 Handler). When the
  controller cancel a Job in the middle of transaction (Scan or Advertising),
  the corresponding buffer pointer is not cleared.
- Memory protection
- CMD disallowed change: Hw Error based recovery worked most of the time. The
  controller sends the Hw Error event (before any exception/watchdog), and then
  the host starts the recovery mechanism. We observed that kernel always sends
  LE Set Advertise Disable or LE Set Scan Disable after reset (SW RF Kill),
  and the controller returns command disallow.
- LE Scan bug: Scanning schedules few milliseconds longer

BUG=b:64035404
TEST=passed AVL(BT Sanity and qualification) and manual testings
