Intel Stratix10 is very the same with Agilex platform, the DWC2 IP on
the Stratix platform also does not support clock-gating. So, based on
commit 3d8d3504d233("usb: dwc2: Add platform specific data for
Intel's Agilex"), combine platform specific data for Intel Agilex and
Stratix10 together. In additional, in order to avoid breaking the old
device tree, keep compatible string "intel,socfpga-agilex-hsotg" unchanged.
