Tom Rini 83d290c56f 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.

/*
* Intel chipset PIRQ routing control ASL description
*
* The programming interface is common to most Intel chipsets. But the PRTx
* registers may be mapped to different blocks. Some chipsets map them to LPC
* device (00:1f:00) PCI configuration space (like TunnelCreek, Quark), while
* some newer Atom SoCs (like BayTrail, Braswell) map them to Intel Legacy
* Block (ILB) memory space.
*
* This file defines 8 PCI IRQ link devices which corresponds to 8 PIRQ lines
* PIRQ A/B/C/D/E/F/G/H. To incorperate this file, the PRTx registers must be
* defined somewhere else in the platform's ASL files.
