watchdog: s3c2410: Minor code cleanup

Cleanup the code from minor readability issues (no functional changes):
1. Fix checkpatch: ERROR: Do not include the paragraph about writing to
   the Free Software Foundation's mailing address.
2. Fix checkpatch: WARNING: quoted string split across lines
3. Fix chechpatch: WARNING: Prefer 'unsigned int' to bare use of
   'unsigned'
4. Use 'dev' consistently in probe function instead of mixing dev with
   &pdev->dev.
