At present sandbox only supports jumping to a file, to get to the next
U-Boot phase. We want to support other methods, so update the code to
use an enum for the method. Also use the
Use board_boot_order() to set the order, so we can add more options.
Also add the MMC methods into the BOOT_DEVICE enum so that booting
from MMC can be supported.

The SPL header has a function for obtaining the phase in capital letters,
e.g. 'SPL'. Add one for lower-case also, as used by sandbox.
Use this to generalise the sandbox logic for determining the filename of
the next sandbox executable. This can provide support for VPL.

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.

At present this is only used on ARM and sandbox, but it is just as
applicable to other architectures. Move the function prototype into the
generic SPL header.

Add an sandbox implementation for the generic SPL framework. This supports
locating and running U-Boot proper.
