rockchip/rk3399: reset system if DDR init fails
We found sdram may fail in pctl_cfg(), so we check the status in this
function. If it exceeds 100ms still in this function, we will restart
the system. We also found there are rare chances DDR training fails,
so also restart system in that case.
BUG=chrome-os-partner:57988
BRANCH=None
TEST=coreboot resets on failure and eventually the system comes up
