There are eMMC boot failures seen with V1P8_SIGNAL_ENA on Kingston
eMMC and variouse types of SD cards on Sitara K3 SoCs due to the
sequencing when enumerating to HS200 mode. Since V1P8_SIGNAL_ENA is
optional for eMMC, do not set V1P8_SIGNAL_ENA by default for eMMC.
For SD cards we shall parse DT for ti,suppress-v1p8-ena property
to determine whether to apply the quirk.

I assume this ti,suppress-v1p8-ena should be added to some SoC dtsi, am I
wrong?


I was planning to add in a separate series once this was merged but I
can add to v3 no problem, thanks for reviewing.
