Revert "mmc: sdhci: Remove unneeded quirk2 flag of O2 SD host controller"
This reverts commit 414126f9e5abf1973c661d24229543a9458fa8ce.
This commit broke eMMC storage access on a new consumer MiniPC based on
AMD SoC, which has eMMC connected to:
02:00.0 SD Host controller: O2 Micro, Inc. Device 8620 (rev 01) (prog-if 01)
Subsystem: O2 Micro, Inc. Device 0002
During probe, several errors are seen including:
mmc1: Got data interrupt 0x02000000 even though no data operation was in progress.
mmc1: Timeout waiting for hardware interrupt.
mmc1: error -110 whilst initialising MMC card
Reverting this commit allows the eMMC storage to be detected & usable
again.
