[Impact]
Platforms with Intel Bluetooth AX201 9462 may hang system during suspend
if it has ever been paired with BLE devices.

[Fix]
Update bluetooth firmware to REL0318 or newer.

[Test Case]
1. pair with BLE devices. They doesn't have to stay connected/powered on
   during the test.
2. make sure Bluetooth is now receiving LE ADV broadcats, which should
   leave messages in dmesg like:

     Bluetooth: hci0: advertising data len corrected

3. suspend the system a few times. With 5.0.0-1025-oem-osp1 kernel,
   symptoms would usually appear in <= 5 times.

[Regression Risk]
Low. This change only updates firmware blob for the specific hardware
affected.
