Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Add MSI support to puc(9)

Add support for MSI interrupts in the puc(9) driver. By default the driver
will prefer MSI interrupts to legacy interrupts. A tunable,
hw.puc.msi_disable, has been added to force the allocation of legacy
interrupts.

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
Discussed with: jhb
- Also while at it, use __FBSDID.

Add location and pnpinfo strings for puc device ports. The location is
announced during boot and contains the port number. The pnpinfo string
lists the port type (PUC_TYPE_* constants).

Fix building with GCC 4.2: ensure types are defined before refering to them.

Rewrite of puc(4). Significant changes are:
o Properly use rman(9) to manage resources. This eliminates the
need to puc-specific hacks to rman. It also allows devinfo(8)
to be used to find out the specific assignment of resources to
serial/parallel ports.
o Compress the PCI device "database" by optimizing for the common
case and to use a procedural interface to handle the exceptions.
The procedural interface also generalizes the need to setup the
hardware (program chipsets, program clock frequencies).
o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
default and non-serdev devices are handled by the bus.
o Use the serdev I/F to collect interrupt status and to handle
interrupts across ports in priority order.
o Sync the PCI device configuration to include devices found in
NetBSD and not yet merged to FreeBSD.
o Add support for Quatech 2, 4 and 8 port UARTs.
o Add support for a couple dozen Timedia serial cards as found
in Linux.

Add missing <sys/module.h> includes

Moved the function pointer in struct puc_device_description to the end
of the struct, so that a placeholder for it (or unportable C99
initializers) are not needed for entries that don't use it. Use a C99
initializer for the 1 entry that uses it. Removed 91 placeholders.
This also restores API compatibility with NetBSD and RELENG_4 for most
entries.

const char ** needs to be passed, not char **.

Use __FBSDID().
Also some minor style cleanups.

Add "missing scratch-pad register" to the first of the two ports
on the Argosy SP-320 dual-port async PCcard.

An amazing piece of hardware seen from an ISO9000 point of view.

Remove a debug printf.

Correctly identify the ARGOSY SP320 dual port serial PCMCIA card.

Stylistic fixes for the inclusion of the opt_puc.h header, so it comes from the
right places, and so it's sorted consistently with how all the other N-hundreds
of files ding this do it.

More cleaning up and unhacking:

Don't expect all RIDs to be PCI rids. The previous code made at
least 1 mistake, even for PCI.

Give the card definitions a chance to specify a init function.
Use this instead of the gross superio hack.
Move the win877 init function to puc_pci.c where it belongs.

RIDs can actually be zero, don't set badmuxed if so.

Set a less incorrect end for the construct SYS_RES_IOPORT entries,
I guess both sio and lpt happen to use 8 IO ports, but that shouldn't
really be hardcoded this way.

Fixup puc_pccard.c to match.

We're getting closer.

Split the puc driver in pci specific and generic parts.
Add a pccard frontend for it as well.

The PCcard stuff does not work yet because there is still some PCImagic
left in puc.c
