Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.
Update the comment in bootstage to refer to this symbol, instead of
SPL_

Use the new symbol to refer to any 'SPL' build, including TPL and VPL

These are not used in TPL so disable the drivers to save space.

At present broadwell only supports booting straight into U-Boot proper.
Add a separate init file to boot from SPL into U-Boot proper, and select
it when SPL is in use.

Split the CPU init into two parts - the 'full' init which happens in the
first U-Boot phase, and the rest of the init that happens on subsequent
stages.

At present, for broadwell, SDRAM is always set up in U-Boot proper since
the 64-bit mode (which uses SDRAM init in SPL) is not supported.
Update the code to allow SDRAM init in SPL instead so that U-Boot proper
can be loaded into SDRAM and run from there. This allows U-Boot to be
compressed to reduce space, since it is not necessary to run it directly
from flash. It could later allow us to support 64-bit U-Boot on broadwell.

The Application Digital Signal Processor is used for sound processing with
broadwell. Add a driver to support this.

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.

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.
