Intel Bluetooth AX201 HarrisonPeak (HrP) [8086:02f0] subsystem [8086:42a4] firmware causes system hang in deep suspend

[You-Sheng Yang]

When system has been paired with BLE devices, bluetooth firmware may fail to suspend, or even hangs the whole system that it can only be rebooted with SysRq keys.

[Reproduce steps]:

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.

[Results]

1. one may observed following errors in between the suspend messages:

     PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -16
     PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -16
     PM: Device 0000:00:14.0 failed to suspend async: error -16
     PM: Some devices failed to suspend, or early wake event detected

   where 0000:00:14.0 is the xHCI Usb hub.

2. with or without above error messages appear first, system may hang and leave only "PM: suspend entry (deep)" in the syslog.

[Notes]

* kernels newer than v5.2.1, inclusive of latest v5.4-rc5, still have those PM suspend errors, but they doesn't seem to cause system block. Instead, they may resume immediately.

* this was found on one platform with Intel Dual Band Wireless AC 9462 [8086:02f0] subsystem id [8086:42a4], linux-firmware 1.173.11 with intel/ibt-19-0-0.sfi REL0282. However, it's not reproducible on another platform with same hw/fw/kernel configuration.
