scsi: ufs: ufs-pci: Set UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE for Intel ADL
commit d968e99488c4b08259a324a89e4ed17bf36561a4 upstream.
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.
