Add usbehci_noncoherent inf-only driver to support USBEHCI on non-cache-coherent devices.

  • Applies to ACPI\RKCP0D20 as well as standard USBEHCI devices (PNP0D20, etc.).
  • Applies to Windows versions 26038 and later.
  • When applied, it loads the in-box usbehci.sys driver and adds the NoInterlockedOpOnCommonBuffers=1 flag.

usbehci - Extension INF for NoInterlockedOpOnCommonBuffers
8892a6e 
Windows 11 2024 release appears to be adding a new registry flag for the
usbehci driver, `NoInterlockedOpOnCommonBuffers`. Setting this flag
appears to resolve the crash on RK3588 systems. Create an Extension-INF
driver that applies this flag.
