phy: qcom-ufs-14nm: Add new compatible for msm8996 based phy 

Add a new compatible string for 14nm ufs phy present on msm8996
chipset. This phy is bit different from the legacy 14nm ufs phy
in terms of the clocks that are needed to be handled in the driver.

@ -7,8 +7,11 @@ To bind UFS PHY with UFS host controller, the controller node should
contain a phandle reference to UFS PHY node.
Required properties:
- compatible : compatible list, contains "qcom,ufs-phy-qmp-20nm"
or "qcom,ufs-phy-qmp-14nm" according to the relevant phy in use.
- compatible : compatible list, contains one of the following -
"qcom,ufs-phy-qmp-20nm" for 20nm ufs phy,
"qcom,ufs-phy-qmp-14nm" for legacy 14nm ufs phy,
"qcom,msm8996-ufs-phy-qmp-14nm" for 14nm ufs phy
present on MSM8996 chipset.
- reg : should contain PHY register address space (mandatory),
- reg-names : indicates various resources passed to driver (via reg proptery) by name.
Required "reg-names" is "phy_mem".
