Each UFS controller instance should have its own node.
Required properties:
-- compatible : compatible list, contains "jedec,ufs-1.1"
+- compatible : must contain "jedec,ufs-1.1", may also list one or more
+ of the following:
+ "qcom,msm8994-ufshc"

- interrupts : <interrupt mapping for UFS host controller IRQ>
- reg : <registers mapping>
Optional properties:
+- phys : phandle to UFS PHY node
+- phy-names : the string "ufsphy" when is found in a node, along
+ with "phys" attribute, provides phandle to UFS PHY node
- vdd-hba-supply : phandle to UFS host controller supply regulator node
- vcc-supply : phandle to VCC supply regulator node
