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.

By default SCI is disabled after power on. ACTL is the register to
enable SCI and route it to PIC/APIC. To support both ACPI in PIC
mode and APIC mode, configure SCI to use IRQ9.

There are no callers now. Platforms which need to set up interrupts their
own way can implement an interrupt driver. Drop this function.

Most x86 interrupt drivers will want to use the standard PIRQ routing and
table setup. Put this code in a common function so it can be used by those
drivers that want it.

At present interrupt routing is set up from arch_misc_init(). We can do it
a little later instead, in interrupt_init().
This removes the manual pirq_init() call. Where the platform does not have
an interrupt router defined in its device tree, no error is generated. Some
platforms do not have this.
Drop pirq_init() since it is no-longer used.

This function can fail. In this case we should return the error rather than
swallowing it.

PIRQ routing is pretty much common in Intel chipset. It has several
PIRQ links (normally 8) and corresponding registers (either in PCI
configuration space or memory-mapped IBASE) to configure the legacy
8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing
support using device tree and move it to a common place, so that we
can easily add PIRQ routing support on a new platform.
