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 we directly pass the Azalia config pointer to the FSP UPD.

So far there are two copies of Azalia struct defines with one in
baytrail and the other one in braswell. This consolidates these
two into one, put it in the common place, and remove the prefix
pch_ to these structs to make their names more generic.
This also corrects reset_wait_timer from us to ms.

At present lpe/lpss-sio/scc FSP properties are all boolean, but in
fact for "enable-lpe" it has 3 possible options. This adds macros
for these options and change the property from a boolean type to
an integer type, and change their names to explicitly indicate what
the property is really for.

The irqroute.asl file is already common enough to all x86 platforms.

Move the irqlinks.asl file currently in the BayTrail directory to

leave the common part in the common file, and move the platform

BayTrail integrates an internal ns15550 compatible UART (PNP0501).
Its IRQ is hardwired to IRQ3 in old revision chipset, but in newer
revision one IRQ4 is being used for ISA compatibility. Handle this
correctly in the ASL file.
Linux does not need this ASL, but Windows need this to correctly
discover a COM port existing in the system so that Windows can
show it in the 'Device Manager' window, and expose this COM port
to any terminal emulation application.

This is a relatively low-cost x86 board in a small form factor. The main
peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800
series CPU. So far only the dual core 2GB variant is supported.
This uses the existing FSP support. Binary blobs are required to make this
board work. The microcode update is included as a patch (all 3000 lines of
it).
