efi_loader: move udevice pointer into struct efi_object
This is a preparation patch to provide the unified method
to access udevice pointer associated with the EFI handle
by adding udevice pointer into struct efi_object.
The patch also introduces a helper function efi_link_dev()
to link the udevice and EFI handle.
The EFI handles of both EFI block io driver implemented in
lib/efi_loader/efi_disk.c and EFI block io driver implemented
as EFI payload can access the udevice pointer in the struct efi_object.
We can use this udevice pointer to get the U-Boot friendly
block device name(e.g. mmc 0:1, nvme 0:1) through EFI handle.
