scsi: ufs-qcom: remove support for save/restore phy configuration
Since support for 28nm phy removed in kernel 3.14, all related code
that is specific to phy 28nm is also removed.
Specifically the quirk that enables save/restore phy configuration
is removed (and all its relevant callbacks) as it's unique to 28nm
ufs phy.
