[WATCHDOG] davinci_wdt clean-up
* Remove the redundant check for pwrite(), given that the open() routine
already invokes nonseekable_open().
* The WDIOF_CARDRESET flag can only be used when you can read this status
via the WDIOC_GETSTATUS ioctl call.
* Add the mandatory WDIOC_GETBOOTSTATUS ioctl call.
