[COMMON] watchdog: s3c2410_wdt: Add multistage watchdog solution

Multistage watchdog is a debugging solution using FIQ
when dumpGPR using reset is not available.

Multistage watchdog has a following policies.

1. Multistage watchdog is big cluster watchdog.
2. When little cluster watchdog is started,
   multistage watchdog is also started.
3. However, if the panic function runs a little cluster watchdog,
   then the multistage watchdog should be turned off.

[COMMON] watchdog: s3c2410_wdt: Add watchdog confirm function.

This function shows the registers associated with the state of the current watchdog.
However, this function does not return, so it must be used only for testing purposes.
