watchdog: s3c2410_wdt: Increase max timeout value of watchdog
Increase max_timeout value from 55s to 3665038s (1018h 3min 58s) with
38400000 frequency system if the system has 32-bit WTCNT register.
cat /sys/class/watchdog/watchdog0/max_timeout
3665038
[ 0.330082] s3c2410-wdt 10060000.watchdog_cl0: Heartbeat: count=1099511400000, timeout=3665038, freq=300000
[ 0.330087] s3c2410-wdt 10060000.watchdog_cl0: Heartbeat: timeout=3665038, divisor=256, count=1099511400000 (fffffc87)
[ 0.330127] s3c2410-wdt 10060000.watchdog_cl0: starting watchdog timer
[ 0.330134] s3c2410-wdt 10060000.watchdog_cl0: Starting watchdog: count=0xfffffc87, wtcon=0001ff39
[ 0.330319] s3c2410-wdt 10060000.watchdog_cl0: watchdog active, reset enabled, irq disabled
If the system has a 32-bit WTCNT, add QUIRK_HAS_32BIT_CNT to its quirk flags,
and it will operate with a 32-bit counter. If not, it will operate with a 16-bit
counter like in the previous version.
