efi_loader: disk: a helper function to create efi_disk objects from udevice
Add efi_disk_probe() function. This function creates an efi_disk object for a raw disk device (UCLASS_BLK) and additional objects for related partitions (UCLASS_PARTITION).
So this function is expected to be called through driver model's "probe" interface every time one raw disk device is detected and activated. We assume that partition devices (UCLASS_PARTITION) have been created when this function is invoked.
