reset: Share struct reset_control between reset_control_get calls
Now that struct reset_control no longer stores the device pointer for the device calling reset_control_get we can share a single struct reset_control when multiple calls to reset_control_get are made for the same reset line (same id / index). This is a preparation patch for adding support for shared reset lines. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
