Thanks for this!  According to my downstream sources this reg is called
cmdq_mem, that's not core indeed.

Tested-by: Marijn Suijten <marijn.suijten@somainline.org> # Sony Xperia 10 II

And also according to my downstream sources, this SoC should support it.
When adding supports-cqe _together with your patch_:

    [    0.391950] sdhci_msm 4744000.mmc: mmc0: CQE init: success

I'll send a followup to that effect.  Thanks again for bringing this to
my attention!
