dedede: Disable system safe mode on IT8320 variants

Disable system safe mode on IT8320 variants. The watchdog period on
IT8320 boards cannot differ from the watchdog period configured in
RO. This means the watchdog period cannot be increased. Since system
safe mode requires a longer watchdog period to operate reliably, it
must be disabled.

IT8320 dedede variants are fixed to the default 1600 WDT period since
this is the period used in most RO images. Note: an RO with a WDT period
longer than 1600 will not cause any critical issues.

BUG=b:416109671
TEST=Watchdog on bookem with 13606.432.0 RO has IPC filled
