start.S: remove double full reset marker 

The Hornet 1.1 seems to have a stability bug when doing full reset. Atheros added
a double full reset mechanism as workaround. It's using a magic to know if they already reset twice.
For uncompressed u-boot's they forgotten to remove they magic after booting normal.
The result is a single reset when doing a "warm" reset.
