watchdog: sbsa_gwdt: clamp WOR value to hw max

The WOR register is 32 bits, so any tick count exceeding U32_MAX is
truncated by writel(). A large requested timeout can wrap to a small
value causing the watchdog to fire sooner than requested.

Clamp the calculated value to U32_MAX prior to writing the register so
over-large requests will be set to the maximum timeout value.
