Series efi_loader: more tightly integrate UEFI disks to driver model | expand

Commit Message

AKASHI Takahiro Dec. 10, 2021, 6:49 a.m. UTC 
With DM-efi_disk integration, we don't need to explicitly call
efi_disk_create_partitions().

The only thing to do is to associate an efi_disk object to
the corresponding udevice as we skip most of processing in
efi_disk_probe() by the previous commit ("efi_loader: disk: not create
BLK device for BLK(IF_TYPE_EFI) devices").
