Add the QMP UFS PHY compatible string for Qualcomm x1e80100 SoC to
support its physical layer functionality for UFS. Use SM8550 as a
fallback since x1e80100 UFS PHY shares the same tech node, allowing
reuse of existing UFS PHY support.

What is a "tech node"?

85 < 87, keep the order by last compatible. It was already screwed by
Xin Liu in previous commit but you do not have to grow discouraged
patterns.

At brief - tech node represents a generation (e.g., 7nm, 5nm, 3nm) of 
semiconductor fabrication technology.
