I don't remember why I removed this line, probably because I
removed S3C_DEV_WDT after there are no references to that
symbol left in board files. The watchdog driver is now DT-only
with cragg6410 being the last remaining board file.

Ideally we should not 'select' it from here but instead have
it enabled in the defconfig file, but I agree that would
be something to do in a separate patch, while the patch here
should not change the behavior. I'll revert this part.

I'm fairly sure this can be removed along with S3C_DEV_WDT,
S3C_DEV_I2C[2-7], S3C_DEV_NAND, and S3C_DEV_ONENAND
as I remove the symbols due to the lack of references
from cragg6410.

I folded in this fixup now:
