[PATCH] watchdog: imx_sc: Remove unnecessary error log

[PATCH] watchdog: imx_sc: Remove unnecessary error log

[Anson.Huang]

From: Anson Huang <Anson.Huang@nxp.com>

An error message is already displayed by watchdog_register_device()
when failed, so no need to have error log again for failure of
calling devm_watchdog_register_device().
