scsi: Forceably finish migration to DM_SCSI

The migration deadline for moving to DM_SCSI was v2023.04. A further
reminder was sent out in August 2023 to the remaining platforms that had
not migrated already, and that a few more over the line (or configs
deleted).

With this commit we:
- Rename CONFIG_DM_SCSI to CONFIG_SCSI.
- Remove all of the non-DM SCSI code. This includes removing other
legacy symbols and code and removes some legacy non-DM AHCI code.
- Some platforms that had previously been DM_SCSI=y && SCSI=n are now
fully migrated to DM_SCSI as a few corner cases in the code assumed
DM_SCSI=y meant SCSI=y.

bootstd: Add a SCSI bootdev

Add a bootdev for SCSI so that these devices can be used with standard
boot.

Move this code into the emulator file so it can be used by multiple

Convert CONFIG_SCSI_AHCI_PLAT et al to Kconfig

This converts the following to Kconfig:
CONFIG_SCSI_AHCI_PLAT
CONFIG_SYS_SCSI_MAX_SCSI_ID
CONFIG_SYS_SCSI_MAX_LUN
CONFIG_SYS_SATA_MAX_DEVICE

Drop CONFIG_SCSI for everything except the sandbox build. We only need
one build for tests.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

scsi: Move drivers into new drivers/scsi directory

At present we have the SCSI drivers in the drivers/block and common/
directories. It is better to split them out into their own place. Use
drivers/scsi which is what Linux does.
