[PATCH AUTOSEL 5.6 045/149] Bluetooth: hci_qca: Not send vendor pre-shutdown command for QCA Rome

[Sasha Levin]

From: Rocky Liao <rjliao@xxxxxxxxxxxxxx>

[ Upstream commit 4f9ed5bd63dc16d061cdeb00eeff9d56e86a6beb ]

QCA Rome doesn't support the pre-shutdown vendor hci command, this patch
will check the soc type in qca_power_off() and only send this command
for wcn399x.

Fixes: ae563183b647 ("Bluetooth: hci_qca: Enable power off/on support during hci down/up for QCA Rome")
