[PATCH V2 09/22] watchdog/mpcore_wdt: Set default heartbeat in probe instead of init

[Viresh Kumar]

Currently mpcore_margin is handled in mpcore_wdt_init routine, which will be
called even if we haven't added any device for watchdog.

This patch moves this code into probe routine, so that it only gets hit once we
add device for this driver.

This also uses dev_info() style print statements instead of printk()
