-100 is -ETIMEDOUT and -84 is CRC error. So that seems much likely HW
relevant. Have you check the SI of SD slot?

You don't enable UHS mode so the tuning process won't help.
But rockchip platforms have a default setting for sample delay.
See rockchip,default-sample-phase and try add some sample delay.
