[0/2] Fixes for the SAMA5D2/SAMA5D4 watchdog

Message

A previous change of the sama5d4_wdt driver broke the device probing
with the device tree configuration described in existing DTS files,
when no value is set for the "timeout-sec" property.

Moreover, specifying any other value than 16 seconds for "timeout-sec"
leads to a watchdog reset immediately when opening the watchdog device.
Fix this by respecting hardware constraints added in recent versions of
the SAMA5D2 and SAMA5D4 datasheet.

Romain Izard (2):
  watchdog: sama5d4: fix timeout-sec usage
  watchdog: sama5d4: write the mode register in two steps
