intr/powerpc: create openpic_class kobj

Using kobj allows implementing most PIC functions merely by inheriting
from the parent class. As there are multiple OpenPIC implementations,
this ensures all common hooks go through by default.

Note, this adds the suspend/resume functions to other PICs. This should
be harmless as suspend/resume isn't working on the devices anyway.

powerpc/mpc85xx: Add MSI support for Freescale PowerPC SoCs

Freescale SoCs use a set of IRQs at the high end of the OpenPIC IRQ
list, not counted in the NIRQs of the Feature reporting register. Some
SoCs include a MSI inbound window in the PCIe controller configuration
registers as well, but some don't. Currently, this only handles the
SoCs *with* the MSI window.

There are 256 MSIs per MSI bank (32 per MSI IRQ, 8 IRQs per MSI bank).
The P5020 has 3 banks, yielding up to 768 MSIs; older SoCs have only one
bank.

The QorIQ SoCs don't actually support multicast interrupts, and the

undefined behavior by binding to only a single CPU, using a quirk to
determine if this is necessary.

that level.

sys/powerpc: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Add suspend/resume state saving for OpenPIC on PowerMac. It's likely this
can be used on the others (cpcht and psim), but that has not been tested.
