After hardware reset, some BCM Bluetooth adapters obtain their initial firmware
from OTPROM chip. Once this initial firmware is running, the firmware can be
further upgraded over HCI interface with .hcd files provided by Broadcom. This
is also known as "patch RAM" support. This change implements that.
If the .hcd file is not found in /lib/firmware, BCM Bluetooth adapter continues
to operate with the initial firmware. Sample kernel log:
hotplug: sys=firmware act=add fw=brcm/BCM20702A0-0a5c-22be.hcd dev=...
Bluetooth: hci0: BCM: patch brcm/BCM20702A0-0a5c-22be.hcd not found
If the .hcd file is found, btusb driver pushes it to the BCM Bluetooth adapter and
it starts using the new firmware. Sample kernel log:
hotplug: sys=firmware act=add fw=brcm/BCM20702A0-0a5c-22be.hcd dev=...
Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=1000 lmp_ver=06 lmp_subver=220e
Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=1389 lmp_ver=06 lmp_subver=220e
Above, we can see that hci_rev goes from 1000 to 1389 as a result of the upgrade.

This reverts commit d2bee8fb6e.
Enabling autosuspend for Intel Bluetooth devices has been shown to not
work reliable. It does work for some people with certain combinations
of USB host controllers, but for others it puts the device to sleep and
it will not wake up for any event.
These events can be important ones like HCI Inquiry Complete or HCI
Connection Request. The events will arrive as soon as you poke the
device with a new command, but that is not something we can do in
these cases.
Initially there were patches to the xHCI USB controller that fixed
this for some people, but not for all. This could be well a problem
somewhere in the USB subsystem or in the USB host controllers or
just plain a hardware issue somewhere. At this moment we just do
not know and the only safe action is to revert this patch.

When stopping BCSP/H5, stop the retransmission timer before proceeding
to clean up packet queues. The previous code had a race condition where
the timer could trigger after the packet lists and protocol structure
had been removed which led to dereferencing NULL or use-after-free bugs.
