I have submitted the patch for stable kernels:
https://patchwork.kernel.org/patch/11297115/

That is a shame. Here is a new patch that disables command queuing which
should avoid the problem. The old patch is then not needed.

I need to see if the value of the SSC1 register changed. It is shown in
the CQHCI REGISTER DUMP looking like "mmc0: cqhci: Task clr: 0x

I would start with a working setup, presumably Ubuntu 18.04. Then get
the latest stable kernel (note, it is possible -rc kernels are broken):

If it doesn't work, please provide kernel messages.

Actually it should apply cleanly to any kernel from 4.17 onward (4.16
would require a little backporting)
To apply the patch, in the linux git directory:
git am 0001-mmc-sdhci-pci-Fix-premature-clock-gating-of-CQHCI-on.patch
