[RFC 15/22] dm: blk: call efi's device-probe hook

AKASHI Takahiro
2021-10-01T05:08:28Z

Adding this callback function, efi_disk_create() in block devices's
post_probe hook will allows for automatically creating efi_disk objects
per block device.

This will end up not only eliminating efi_disk_register() called in UEFI
initialization, but also enabling detections of new block devices even
after the initialization.
