watchdog: omap_wdt: Fix WDT target reset when booted from emmc
AM335X based beaglebone black target gets reset by DM converted watchdog
if booted from emmc around 60sec. Fixed this by moving driver's private struct
variable initialization at different places in the driver to driver's probe.
Tested on Beaglebone Black.
