scsi: ufs: core: Restore SM8650 support
Some early UFSHCI 4.0 controllers support the UFSHCI 3.0 register set.
The UFSHCD_QUIRK_BROKEN_LSDBS_CAP quirk must be set for these controllers.
Commit b92e5937e352 ("scsi: ufs: core: Move code out of an if-statement")
changed the behavior for these controllers from working fine into
"ufshcd_add_scsi_host: failed to initialize (legacy doorbell mode not
supported)". Fix this by setting the "broken LSDBS" quirk for the
SM8650 development board.
