i2c: s3c2410: Drop S3C2410 OF support

Samsung S3C2410 SoC was removed from the Linux kernel in the
commit 61b7f892 ("ARM: s3c: remove all s3c24xx support"), in January
2023.  There are no in-kernel users of "samsung,s3c2410-i2c" compatible.

However, there is still a user of "s3c2410-i2c" platform device ID,
S3C64xx platform, so that part needs to stay.
