USB Root Hub INF on builds (RS5 or earlier) with broken XHCI driver. On these builds, the Hardware ID of the root hub would become B\ROOT_HUB30# instead of the normal USB\ROOT_HUB30 and the stock INF will fail to work.
The new RPi3.ARM64 and RPi4.ARM64 BSP will be side by side with the existing RPi ARM32 BSP for RPi2/3. Move RPi to its own directory to avoid conflition. binexport scripts will be updated when the new BSPs are added.
While trying to upstream a revert patch does not make much sense, one can try to make a patch that will allow to switch between MS-specific function and the standard The switch can be then added to the UEFI setup application. |

This adds two new BSPs: RPi3.ARM64 and RPi4.ARM64.
Currently they require UEFI firmware from PFTF to be manually added to
bspfiles/RPix.ARM64/Packages/RPi.BootFirmwarebefore exporting the BSP.Also the proprietary USB and LAN drivers for Pi3 are not included, and have to be manually added.
A special INF file, rpirshub3.inf, is added to bring up XHCI on Pi 4 on Windows builds <= RS5.
