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.

Adds HDIF_get_iarray() which retrieves and validates an internal array
header and HDIF_iarray_for_each() for walking the individual array
entries. This reduces the amount of get-then-check boilerplate that
we have with the existing HDIF_get_iarray_item() method for iterating
internal data arrays.

Currently these aren't sufficently obnoxious, so make them more so. HDAT
parse errors usually mean we won't be able to generate enough of a
device-tree to boot so we want to make this much more obvious.

The HDAT has very fixed relationships between a parent and child
structures. When parsing the HDAT we always know what type of child
that we expect and we will error out if there is a mismatch between what
we get and what expect. This patch just prints out what we got in
addition to what we expected to help with debugging.
