Subject: [v2 PATCH] arm64: dts: stratix10: add new compatible for Intel SoCFPGA Stratix10 platform

Intel Stratix10 is very the same with Agilex platform, the DWC2 IP on
the Stratix platform also does not support clock-gating. The commit
3d8d3504d233("usb: dwc2: Add platform specific data for Intel's Agilex")
had fixed this issue. So, add the essential compatible to also use the
specific data on Stratix10 platform.

v2:
 - Add SoC specific compatible as per Krzysztof comment
