allow ACPI to compile without PCI support. fixes ia64 build.

acpi(9): Return full 64-bit object to caller in PCI config read.

The value of the object will be as small as requested, but the whole
uint64_t object will be written as the caller of a space handler
expects, instead of just part of it.

Add support for Arm N1 SDP PCIe host controller.

The N1 SDP has a few bugs that we need to work around:
- PCIe root port config space lives in a non-standard location.
- Access to PCIe config space of devices that do not exist results in
an sync SError. Firmware creates a "known devices" table at a fixed
physical address that we use to filter PCI conf access to only known
devices.

This change splits the Arm ACPI PCI quirks into separate files for each
host controller, and allows per-segment quirks to be applied.

These changes exposed some bugs in the MI ACPI layer related to
multi-segment support. The MI ACPI PCI code was using a shared PCI
chipset tag to access devices, and these accesses can happen before our
PCI host bridge drivers are attached! The global chipset tag is now gone,
and an MD callback can provide a custom tag on a per-segment basis.

Fixed a problem with the prototype for AcpiOsReadPciConfiguration.
The prototype in acpiosxf.h had the output value pointer as a (void *).
It should be a (UINT64 *). This may affect some host OSL code.

ACPICA 20100915:

Removed the AcpiOsDerivePciId OSL interface. The various host
implementations of this function were not OS-dependent and are now obsolete
and can be removed from all host OSLs. This function has been replaced by
AcpiHwDerivePciId, which is now part of the ACPICA core code.
AcpiHwDerivePciId has been implemented without recursion. Adds one new
module, hwpci.c. ACPICA BZ 857.

Move from sys/dev/acpi/acpica/Osd.

Allow registering ACPI interrupt handlers with a xname.
AcpiOsInstallInterruptHandler(), part of ACPICA API, doesn't allow passing
the xname. I extend the API with AcpiOsInstallInterruptHandler_xname()
for this purpose, and change acpi_md_OsInstallInterruptHandler() to
accept and use the xname (ia64 doens't use it).
The xname was hardcoded to "acpi SCI" in the
x86 acpi_md_OsInstallInterruptHandler(), so I make
AcpiOsInstallInterruptHandler() call
AcpiOsInstallInterruptHandler_xname with xname = "acpi SCI".

Now 'vmstat -i' shows the device's name instead of "acpi SCI" for for i2c HID
interrupts.

Remove also the debug-printf in case of long Stall() requests;

/*
* sleep(9) isn't safe because AcpiOsStall may be called
* with interrupt-disabled. (eg. by AcpiEnterSleepState)
* we should watch out for long stall requests.
*/

ACPICA has long printed a similar warning by itself. Moreover, this message
was never reached as the interpreter does not invoke AcpiOsStall() when a
delay longer than 255 usec is requested.

Remove the recently added warning about long Sleep() requests.

This is now in ACPICA (20100528):

Added support to limit the maximum time for the ASL Sleep()
operator. To prevent accidental deep sleeps, limit the maximum time
that Sleep() will actually sleep. Configurable, the default maximum
is two seconds. ACPICA bugzilla 854.

Print a warning if AcpiOsSleep() is called with a value larger than two
seconds. It is known that there are systems in the field that pass bogus AML
values to the Sleep() operation code, possibly requesting delays that could
be measured in days.

Discussed with jmcneill@.

XXX: While the used mstohz(9) is documented to round to one second if the
passed value is larger than 131072 ms, we may still need to force a
sensible upper limit if this warning starts to appear.
