x86: Use multiple images

We already use binman's 'multiple-images' feature with Chrome OS and we
want to use it for Edison. There is no real down-side.

Adjust x86 to always use multiple-images.

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.

x86: quark: Fix build error for quark-based boards

With the conversion to use binman to build x86 boards, Intel Galileo
board does not build anymore due to missing ucode entry. In fact
ucode is not needed for quark-based boards.
