[PATCH 0/6] env: scsi: support SCSI env without partition UUID

This is a series adding support for reading U-Boot env directly from
SCSI devices that do not have a partition table, similar to how we can
already do this for MMC devices.

The motivation behind this is that MediaTek's BSP is already using the
same disk images for both MMC and UFS devices, so we need to be able to
read the env from SCSI devices without requiring a partition UUID.

The series starts with cleaning up a few oddities we noticed in the
existing code. Then some refactoring so that the env code manages
calling scsi_scan() so that we don't have to duplicate that for the
new code path. Then finally, the last few patches add and document the
new functionality.
