Like on the SAMA5D2 and SAMA5D4 Xplained boards,
enable the watchdog device on the SAMA5D3 Xplained board.
As explained on drivers/watchdog/at91sam9_wdt.c,
for the watchdog driver to work in Linux, you need to make sure
that the bootstrap / bootloader doesn't disable the watchdog,
as the Watchdog Timer Mode Register can be only written to once.
