Subject: [PATCH] scsi: ufs: ufs-pci: Set
 UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE for Intel ADL

Link startup becomes unreliable for Intel Alder Lake based host
controllers when a 2nd DME_LINKSTARTUP is issued unnecessarily.  Employ
UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE to suppress that from happening.
