It was though all ES revisions of H3 and M3-W SoCs required the TMIO_MMC_HAVE_4TAP_HS400 flag. Recent datasheet updates tells us this is not true, only early ES revisions of the SoC do. Since quirk matching based on ES revisions is now used to handle the flag it's possible to align all Gen3 compatibility properties. This will allow later ES revisions of H3 and M3-W to use the correct 8-tap HS400 mode.
