reset: Add devm_reset_control_get_optional_exclusive_released() 



NVIDIA Tegra DRM and media drivers will need a resource-managed-optional
variant of reset_control_get_exclusive_released() in order to switch away
from a legacy Tegra-specific PD API to a GENPD API without much hassle.
Add the new reset helper to the reset API.
