i3c: master: dw-i3c: Fix missing reset assertion in remove() callback

[ Upstream commit bef1eef ]

The reset line acquired during probe is currently left deasserted when
the driver is unbound.

Switch to devm_reset_control_get_optional_exclusive_deasserted() to
ensure the reset is automatically re-asserted by the devres core when
the driver is removed.
