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.

Broadwell uses a binary blob called the memory reference code (MRC) to start
up its SDRAM. This is similar to ivybridge so we can mostly use common code
for running this blob.

Broadwell requires quite a bit of power-management setup. Add code to set
this up correctly.

Add a driver for the broadwell LPC (low-pin-count peripheral). This mostly
uses common code.

GPIO pins need to be set up on start-up. Add a driver to provide this,
configured from the device tree.
The binding is slightly different from the existing ICH6 binding, since that
is quite verbose. The new binding should be just as extensible.

This adds the broadwell architecture, with the CPU driver and some useful
header files.
