Subject: scsi: ufs: Add quirk to fix mishandling utrlclr/utmrlclr
Git-commit: 871838412adf533ffda0b4a0ede0c2984e3511e7
Patch-mainline: v5.9-rc1
References: bsc#1186995

With the correct behavior, setting the bit to '0' indicates clear and '1'
indicates no change. If host controller handles this the other way around,
UFSHCI_QUIRK_BROKEN_REQ_LIST_CLR can be used.
