arm: Shorten the Firmware Update (FWU) process
The watchdog is configured with a default value of 256 seconds in order
to implement the Trusted Board Boot Requirements.
For the FVP and Juno platforms, the FWU process relies on a watchdog
reset. In order to automate the test of FWU, the length of this process
needs to be as short as possible. Instead of waiting for those 4 minutes
to have a reset by the watchdog, tell it to reset immediately.
There are no side effects as the value of the watchdog's load register
resets to 0xFFFFFFFF.
Tested on Juno.
