[WATCHDOG] i6300.h-removal-patch

the attached patch moves the content of drivers/char/watchdog/i6300.h
into drivers/char/watchdog/i6300.c, since it is the only file using the
defines there is no real reason to have a separate header.

Also cleaned up the comments a bit and added myself to the copyright
holders.
