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: kconfig: Remove meaningless 'select n'

'select n' selects a constant symbol, which is meaningless and has no
effect. Maybe this was meant to be a 'default n', though bool and
tristate symbols already implicitly default to n.

Discovered in Kconfiglib (https://github.com/ulfalizer/Kconfiglib),
which does more strict checking here:

x86: Add support for the samus chromebook

This adds basic support for chromebook_samus. This is the 2015 Pixel and
is based on an Intel broadwell platform.

Supported so far are:
- Serial
- SPI flash
- SDRAM init (with MRC cache)
- SATA
- Video (on the internal LCD panel)
- Keyboard

Various less-visible drivers are provided to make the above work (e.g. PCH,
power control and LPC).

The platform requires various binary blobs which are documented in the
README. The major missing feature is USB3 since the existing U-Boot support
does not work correctly with Intel XHCI controllers.
