Subject: [PATCH v2 2/9] watchdog: keembay: Upadate WDT pretimeout for every update in timeout

From: Shruthi Sanil <shruthi.sanil@...el.com>

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.
