You still need the same workaround 8550/8650 have in the UFS driver
(UFSHCD_QUIRK_BROKEN_LSDBS_CAP) for it to work reliably, or at least
that was the case for me on a 8750 QRD.

Please check whether we can make that quirk apply based on ctrl
version or so, so that we don't have to keep growing the compatible
list in the driver.
