aspeed/watchdog: Correct timeout value
The driver was using milliseconds and programming it into a register
which takes ticks of the watchdog clock, which runs at 1MHz. This meant
we were off by 1000 with the desired value.
When 06985289d452 ("watchdog: Implement generic watchdog_reset()
version") was added the aspeed board would leave the watchdog running,
causing it to bite before u-boot was done.
Discovered by booting in qemu:
$ qemu-system-arm -M ast2500-evb -drive file=test.img,format=raw,if=mtd -nographic -no-reboot -d cpu_reset
