--------------------------------

[ Upstream commit df640778 ]

The bus sdw_drv_remove() and sdw_drv_shutdown() helpers are used
conditionally, if the driver provides these routines.

These helpers already test if the driver provides a .remove or
.shutdown callback, so there's no harm in invoking the
sdw_drv_remove() and sdw_drv_shutdown() unconditionally.

In addition, the current code is imbalanced with
dev_pm_domain_attach() called from sdw_drv_probe(), but
dev_pm_domain_detach() called from sdw_drv_remove() only if the driver
provides a .remove callback.
