I just hacked my local branch to fix the issues found on rockchip
platform. The reaseon is that mmc core fail to get status
after switching from hs200 to hs. So I disabled sending status for it
just like what Chaotian does here. But I didn't deeply dig out the root
cause but I

Per JEDEC spec, it is not recommended to use CMD13 to get card status
after speed mode switch. below are two reason about this:
1. CMD13 cannot be guaranteed due to the asynchronous operation.
Therefore it is not recommended to use CMD13 to check busy completion
of the timing change indication.
2.
