scsi: ufs-qcom: enable quirk to fix gear change to HS 

With the G3 UFS devices, changing gear into HS is failing in UFS host
controllers of version 0x2.
The quirk solves the problem of changing gear into HS by enabling
the attribute that specifies whether or not the inbound Link supports
unterminated line in HS mode.
