[PATCH v2 0/2] efi_loader: support all uclasses in device path

On devices with multiple USB mass storage devices errors like

Path /../USB(0x0,0x0)/USB(0x1,0x0)/Ctrl(0x0) already installed.

are seen. This is due to creating non-unique device paths. To uniquely identify devices we must provide path nodes for all devices on the path from the root device.

Add support for generating device path nodes for all uclasses.

v2: Add a prerequisite patch for BLKMAP, HOST, VIRTIO block devices
