Subject: [PATCH AUTOSEL 6.6 022/139] Bluetooth: btrtl: Set msft ext address filter quirk for RTL8852B

From: Hilda Wu <hildawu@...ltek.com>

[ Upstream commit 9a0570948c5def5c59e588dc0e009ed850a1f5a1 ]

For tracking multiple devices concurrently with a condition.
The patch enables the HCI_QUIRK_USE_MSFT_EXT_ADDRESS_FILTER quirk
on RTL8852B controller.

The quirk setting is based on commit 9e14606d8f38 ("Bluetooth: msft:
Extended monitor tracking by address filter")

With this setting, when a pattern monitor detects a device, this
feature issues an address monitor for tracking that device. Let the
original pattern monitor keep monitor new devices.
