reset: add of_reset_control_get_by_index()
Add of_reset_control_get_by_index() to allow the drivers to get reset device without knowing its name. Signed-off-by: Vince Hsu <vinceh@nvidia.com> [jonathanh@nvidia.com: Updated stub function to return -ENOTSUPP instead of -ENOSYS which should only be used for system calls.] Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
