Subject[PATCH] fix 5.15 init regression for Intel Bluetooth

Hi

On all 5.15 kernels the Intel Bluetooth no longer works. All was fine in 5.14.
Apparently the quirk is needed for this device.

vanilla 5.15.5:
Bluetooth: hci0: Reading Intel version command failed (-110)
Bluetooth: hci0: command tx timeout

with patch:
Bluetooth: hci0: Legacy ROM 2.5 revision 1.0 build 3 week 17 2014
Bluetooth: hci0: Intel device is already patched. patch num: 32

Please apply to stable too.

Thanks
