SPDX makes it a simpler diff.
I have audited the commit history of each file to ensure that they are
exclusively authored by IBM and thus we have the right to relicense.
The motivation behind this is twofold:
1) We want to enable experiments with coreboot, which is GPLv2 licensed
2) An upcoming firmware component wants to incorporate code from skiboot
and code from the Linux kernel, which is GPLv2 licensed.
I have gone through the IBM internal way of gaining approval for this.
The following files are not exclusively authored by IBM, so are *not*
included in this update (I will be seeking approval from contributors):

Use Software Package Data Exchange (SPDX) to indicate license for each
file that is unique to skiboot.
At the same time, ensure the (C) who and years are correct.

It's been a good long while since either OPAL POWER7 user touched a
machine, and even longer since they'd have been okay using an old
version rather than tracking master.
There's also been no testing of OPAL on POWER7 systems for an awfully
long time, so it's pretty safe to assume that it's very much bitrotted.
It also saves a whole 14kb of xz compressed payload space.

Currently in NX, only write xscom config failures are tracing.
Add trace statements for read xscom config failures too.
No functional changes.

The NX rng BAR is used by each core to source random numbers for the
DARN instruction. Currently we configure each core to use the NX rng of
the chip that it exists on. Unfortunately, the NX can be deconfigured by
hostboot and in this case we need to use the NX of a different chip.
This patch moves the BAR assignments for the NX into the normal nx-rng
init path. This lets us check if the normal (chip local) NX is active
when configuring which NX a core should use so that we can fallback
gracefully.

"ibm, power9-nx" should be "ibm,power9-nx" and the mismatch was
causing nuisance errors at boot.

A few places (mostly old code) were using:
add_property_cells(hi32(number), lo32(number));
This patch converts them to use the helper rather than doing it manually.

Add NX config register values for P7+. Remove "P8" from all register
defines, where the define is common to P7+ and P8. For values new to P8
(specifically 842 prefeching), only enable on P8.
This should correctly setup the NX coprocessors on P7+ systems.

Add support for the 842 hw memory compression engine in the NX Coprocessor.
This moves the existing RNG support into its own nx-rng.c file, adds 842
support in a nx-842.c file, and creates a nx-crypto.c file to configure and
disable the crypto engines (which are not supported yet).
New nodes are created for each 842 engine found. This does not actually
process any of the data or drive the 842 engines, it only configures
registers to set up and enable/disable the engines appropriately, and
creates new nodes so the OS can drive the 842 engines.
