watchdog: imx7ulp_wdt: Fix RCS timeout issue
According to measure on i.MX7ULP and i.MX8ULP, the RCS done needs
about 3400us and 6700us respectively. So current 20us timeout is
not enough. When reconfiguring is on-going, unlock and configure CS
will lead to unknown result.
Increase the wait timeout value to 10ms and check the return value
of RCS wait to fix the issue
