watchdog: imx2_wdt: add pretimeout function support
The change adds watchdog pretimeout notification handling to imx2_wdt driver, if device data contains information about a valid interrupt. It is unlikely but still possible (e.g. through a software limitation) that only a subset of watchdogs on SoC has interrupt lines, hence functionally the devices from these two groups have different capabilities, and this is reflected in different watchdog_info structs assigned to the devices.
