[PATCH linux 3/3] watchdog/aspeed_wdt: Set system reset mode to 'full chip'

[OpenBMC Patches]

From: Jeremy Kerr <jk at ozlabs.org>

Currently, the watchdog timer does nothing on expiry - the 'SoC system'
reset type doesn't seem to have any effect.

This change uses the 'full chip' reset type instead.
