watchdog: msc313e: Fix premature reset during timeout update
Updating the 32-bit hardware timeout requires writing to two 16-bit
registers sequentially. If the watchdog is actively running, this
non-atomic update might trigger a premature system reset.
Clear the watchdog counter before updating the registers to prevent the
timer from timing out prematurely against an intermediate threshold.
