commit 7ecacafc24 upstream.
After commit 9e45524a01 ("Bluetooth: btusb: Fix suspend issue for
Realtek devices") both WiFi and Bluetooth stop working after reboot:
[ 34.322617] usb 1-8: reset full-speed USB device number 3 using xhci_hcd

[ 44.599493] rtw_pci 0000:02:00.0: failed to leave idle state
That commit removed USB_QUIRK_RESET_RESUME, which not only resets the USB
device after resume, it also prevents the device from being runtime
suspended by USB core. My experiment shows if the Realtek btusb device
ever runtime suspends once, the entire wireless module becomes useless
after reboot.
So let's explicitly disable runtime suspend on Realtek btusb device for
now.

From the perspective of controller, global suspend means there is no
SET_FEATURE (DEVICE_REMOTE_WAKEUP) and controller would drop the
firmware. It would consume less power. So we should not send this kind
of SET_FEATURE when host goes to suspend state.
Otherwise, when making device enter selective suspend, host should send
SET_FEATURE to make sure the firmware remains.

This reverts commit a0085f2510.
This commit has caused regressions in notebooks that support suspend
to idle such as the XPS 9360, XPS 9370 and XPS 9380.
These notebooks will wakeup from suspend to idle from an unsolicited
advertising packet from an unpaired BLE device.
In a bug report it was sugggested that this is caused by a generic
lack of LE privacy support. Revert this commit until that behavior
can be avoided by the kernel.

For the Marvell HCI UART we have to upload two firmware files. The first
one is only for switching the baudrate of the device to a higher
baudrate. After the baudrate switching firmware has been uploaded the
device waits for a final ack (0x5a) before actually switching the
baudrate. To send this final ack with the old baudrate give the hci
ldisc workqueue a chance to run before switching the baudrate. Without

Firmware download to the WCN3990 often fails with a 'TLV response size

[ 133.513265] Bluetooth: hci0: QCA Failed to download patch (-84)
This is caused by a vendor event that corresponds to an earlier command
to change the baudrate. The event is not processed in the context of the
baudrate change and is later interpreted as response to the firmware
download command (which is also a vendor command), but the driver detects
that the event doesn't have the expected amount of associated data.
More details:
For the WCN3990 the vendor command for a baudrate change isn't sent as
synchronous HCI command, because the controller sends the corresponding
vendor event with the new baudrate. The event is received and decoded
after the baudrate change of the host port.
Identify the 'unused' event when it is received and don't add it to
the queue of RX frames.
