watchdog: it87_wdt: Add IT8659 ID



This patch adds watchdog support for the ITE IT8659 watchdog.
IT8659 watchdog works in the same way as the other watchdogs supported
by it87_wdt.

Before this patch, IT8659 watchdog is not supported. After a modprobe,
dmesg reports:
  it87_wdt: Unknown Chip found, Chip 8659 Revision 0007

With this patch, modprobe it87_wdt recognizes the watchdog as the dmesg
output shows:
  it87_wdt: Chip IT8659 revision 7 initialized. timeout=60 sec (nowayout=0
  testmode=0)

Watchdog tests on a YANLING YL-ALP3L2C-1235U system have been successful,
the watchdog works as expected with this patch.
