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.
