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.
