watchdog: it87_wdt: add IT8613 ID

This patch adds watchdog support for the ITE IT8613 watchdog.
IT8613 watchdog works in the same way as the other watchdogs supported
by it87_wdt.

Before this patch, IT8613 watchdog is not supported. After a modprobe,
dmesg reports:
  it87_wdt: Unknown Chip found, Chip 8613 Revision 000c
With this patch, modprobe it87_wdt recognizes the watchdog as the dmesg
output shows:
  it87_wdt: Chip IT8613 revision 12 initialized. timeout=60 sec (nowayout=0 testmode=0)

Watchdog tests on a LES v4 have been successful, the watchdog works as
expected with this patch [1].
