Since UFSHCI 4.0 controllers must support UFSHCI 3.0, shouldn't users have a way to disable MCQ, e.g. via a kernel module parameter?

I can add a kernel module parameter to disable MCQ.
I think adding it to host driver (e.g. ufs-qcom) would be good.
Please let me know if you have a better place in mind.

Since this functionality is useful for all host controllers please add it in the core UFS host controller driver (drivers/ufs/core/ufshcd.c).

Thanks,

Bart.
