watchdog: s3c2410_wdt: Drop S3C2410 support

Samsung S3C2410 SoC was removed from Linux kernel in the
commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support"), in January
2023.  There are no in-kernel users of samsung,s3c2410-wdt compatible
and s3c2410-wdt platform device name, so drop both.  This leaves the
driver boundable only via compatibles, so drop any CONFIG_OF ifdefs.
