soc/amd/stoneyridge: Enable spread spectrum in bootblock
setup_spread_spectrum is called in early_init, meaning the console is
not initialized yet. So you won't see boot block booting twice.
BUG=b:111610455
TEST=booted grunt and verified that AmdInitReset does not reboot. I had
AGESA patched to skip the JTAG check.
