Andrey Smirnov 39d0387d5e watchdog: ziirave_wdt: Don't bail out on unexpected timeout value
Reprogramming bootloader on watchdog MCU will result in reported
default timeout value of "0". That in turn will be unnecessarily
rejected by the driver as invalid device (-ENODEV). Simplify probe to
read stored timeout value, set it to a sane default if it is bogus,
and then program that value unconditionally.
