Jorge Ramirez-Ortiz 8563ec5a46 dt-bindings: Add Qualcomm USB SuperSpeed PHY bindings
Binding description for Qualcomm's Synopsys 1.0.0 SuperSpeed PHY. This PHY
appears in a number of SoCs on various flavors of 20nm and 28nm nodes.

This commit adds information related to the 28nm node only.

Based on Sriharsha Allenki's <sallenki@codeaurora.org> original
definitions.
