sys: general 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.

No functional change intended.

MFC 196520:
Tweak the way that the ACPI and ISA bus drivers match hint devices to
BIOS-enumerated devices:
- Assume a device is a match if the memory and I/O ports match even if the
IRQ or DRQ is wrong or missing. Some BIOSes don't include an IRQ for
the atrtc device for example.
- Add a hack to better match floppy controller devices. Many BIOSes do not
include the starting port of the floppy controller listed in the hints
(0x3f0) in the resources for the device. So far, however, all the BIOS
variations encountered do include the 'port + 2' resource (0x3f2), so
adjust the matching for "fdc" devices to look for 'port + 2'.

Allow device hints to wire the unit numbers of devices.
- An "at" hint now reserves a device name.
- A new BUS_HINT_DEVICE_UNIT method is added to the bus interface. When
determining the unit number of a device, this method is invoked to
let the bus driver specify the unit of a device given a specific
devclass. This is the only way a device can be given a name reserved
via an "at" hint.
- Implement BUS_HINT_DEVICE_UNIT() for the acpi(4) and isa(4) bus drivers.
Both of these busses implement this by comparing the resources for a
given hint device with the resources enumerated by ACPI/PnPBIOS and
wire a unit if the hint resources are a subset of the "real" resources.
- Use bus_hinted_children() for adding hinted devices on isa(4) busses
now instead of doing it by hand.
- Remove the unit kludging from sio(4) as it is no longer necessary.

Remove old GENERIC kludge. We no longer need to skip devices named
atkbd. Version 1.162 of GENERIC fixed this problem in April of 1999.
Subsequent to that, the hints data was removed from GENERIC and move
to hints files. All the hints file ever created have atkbd at the
right location. This should have been removed just after RELENG_4 was
branched (and likely around 4.5 in RELENG_4).

- Use the new resource_disabled() helper function to see if devices are
disabled.
- Change the apm driver to match the acpi driver's behavior by checking to
see if the device is disabled in the identify routine instead of in the
probe routine. This way if the device is disabled it is never created.

Note that a few places (ips(4), Alpha SMP) used "disable" instead of
"disabled" for their hint names, and these hints must be changed to
"disabled". If this is a big problem, resource_disabled() can always be
changed to honor both names.

fixed a long while ago.
- Provide some much more flexible search functions (resource_find_*())
- Use strings for storage instead of an outgrowth of the rather
inconvenient temporary ioconf table from config(). We already had a
fallback to using strings before malloc/vm was running anyway.

Always call resource_int_value function for getting portsize and msize.
It was not set resource size (portsize/msize) if resource address was set.

This is MFC candidate.

Repeat after me: I will test *before* commit, not after.... *blush*

Untangle some resource matching loops that were getting on my nerves
and seemed to be getting cut/pasted to places they shouldn't be.

Allow a DMA channel of 0. This gets the on-board mss audio device working

resource_list_release. This removes the dependancy on the
layout of ivars.

* Add struct resource_list* argument to resource_list_alloc and

layout of ivars.

* Move set_resource, get_resource and delete_resource from
isa_if.m to bus_if.m.

* Simplify driver code by providing wrappers to those methods:

bus_set_resource(dev, type, rid, start, count);
bus_get_resource(dev, type, rid, startp, countp);
bus_get_resource_start(dev, type, rid);
bus_get_resource_count(dev, type, rid);
bus_delete_resource(dev, type, rid);

* Delete isa_get_rsrc and use bus_get_resource_start instead.

* Fix a stupid typo in isa_alloc_resource reported by Takahashi
Yoshihiro <nyan@FreeBSD.org>.

* Print a diagnostic message if we can't assign resources to a PnP
device.

* Change device_print_prettyname() so that it doesn't print
"(no driver assigned)-1" for anonymous devices.
