arm64: acpi: Honour DMA memory address limit for named components.

Use "non-posted" instead of "strongly ordered" to describe nGnRnE mappings

Rename the following defines:
 - _ARM_BUS_SPACE_MAP_STRONGLY_ORDERED to BUS_SPACE_MAP_NONPOSTED
 - PMAP_DEV_SO to PMAP_DEV_NP
 - LX_BLKPAG_ATTR_DEVICE_MEM_SO to LX_BLKPAG_ATTR_DEVICE_MEM_NP
Rename the following option:
 - AARCH64_DEVICE_MEM_STRONGLY_ORDERED to AARCH64_DEVICE_MEM_NONPOSTED

arm: ACPI: Add support for simple sharing of platform interrupts

Allow sharing of platform interrupts provided that the type, ipl, and
mpsafe-ness are the same.

acpi: DMA: Use acpi_resource_parse_any to parse _DMA resources

_DMA resources really should be marked ResourceProducer, so use
acpi_resource_parse_any to pick these up.

Merge thorpej-cfargs2.

Adapt to CFARGS().

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
  actually needed.
- Don't be explicit about what interface attribute is attaching if
  the device only has one.  (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
  situations, making is visibly easier to see when indirect config is
  in play, and allowing for future change in semantics.  (As of now,
  this is just a wrapper around config_match(), but that is an
  implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance.  This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

acpi_md_gtdt_probe(): Fix paste-o in interface attribute name.

config_found_ia() -> config_found() w/ CFARG_IATTR.

Sync w/ HEAD.

Add MI support for attaching drivers to arbitrary System Description
Tables.

Provide a properly constrained 32-bit DMA tag to ACPI.

Rely on 32/64-bit overflow to calculate translation offsets. Store this
as a separate ar_xbase field in acpi_mem instead of having separate
ar_offset and ar_decode fields.

Create bus_dma tags for each device node based on _CCA and _DMA properties
found by walking up the device node tree. These tags encode range
restrictions, address translations, and whether or not the device is
cache coherent.

The DMA restrictions may not be defined in the direct parent of a device,
so search up the tree for a module device.

If a device node is a child of a module device, and the module device declares DMA range restrictions, use them.

Allow MD code to provide custom bus_dma tags on a per-node basis. On Arm
this is required to return non-coherent bus_dma tags for device nodes with
_CCA=0

Enable early write acknowledge for device memory mappings.

Do not use Early Write Acknowledge for PCIe I/O and config space.

Do not use Early Write Acknowledge for PCIe I/O and config space.

Implement acpi_md_intr_mask and acpi_md_intr_unmask

Add acpi_intr_mask() and acpi_intr_unmask() which, following the pre-existing
ACPI software layering model, are wrappers around acpi_md_intr_mask() and
acpi_md_intr_unmask(), which in turn are wrappers around intr_mask() and
intr_unmask().

XXX ARM and IA64 implementations of acpi_md_intr_mask() and
acpi_md_intr_unmask() are just stubs for now.
