rockchip/rk3399: sdram: Reset system if switch to index1 fails
Near the end of DDR initialization, the system switches to the index1
configuration. Sometimes this failed and a status bit that coreboot was
waiting for was never set, hanging the system.
Instead, give the system 100ms to reach the new configuration or reboot
it, which generally fixes the issue. Also reset when training the index1
configuration fails.
BUG=chrome-os-partner:57988
BRANCH=None
TEST=The error condition now leads to a reboot of coreboot which
recovers the system, instead of hanging.
