[PATCH 6.6.y 3/4] Bluetooth: hci_qca: Migrate to serdev specific shutdown function

[Sasha Levin <sashal@kernel.org>]

From: Uwe Kleine-König <u.kleine-koenig@baylibre.com>

[ Upstream commit 12a6a5726c515455935982429ac35dee2307233d ]

This saves a cast in the driver. The motivation is stop using the callback
.shutdown in qca_serdev_driver.driver to make it possible to drop that.
