[ Upstream commit 0f7bfaf10c0abc979220442bae2af4f1f869c41e ]
The pre-timeout value to be programmed to the register has to be
calculated and updated for every change in the timeout value.
Else the threshold time wouldn't be calculated to its
corresponding timeout.
Fixes: fa0f8d51e90d ("watchdog: Add watchdog driver for Intel Keembay Soc")
