Subject: [PATCH 5.18 170/879] Bluetooth: btusb: Set HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN for QCA

From: Luiz Augusto von Dentz <luiz.von.dentz@...el.com>

[ Upstream commit d44e1dbda36fff5d7c2586683c4adc0963aef908 ]

This sets HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN for QCA controllers
since SCO appear to not work when using HCI_OP_ENHANCED_SETUP_SYNC_CONN.
