Add function pci_check_pme_status() that will check the PME status
bit of given device and clear it along with the PME enable bit. It
will be necessary for PCI run-time power management.

BIOS separates IO ranges between several IOHs, and on some slots, BIOS assigns
resources to a bridge, but stops assigning resources to the device under that
bridge, because the device needs a big resource.
So:
1. allocate resources and record the failed device resources
2. clear the BIOS assigned resources of the parent bridge of failing device
3. go back and call pci assign unassigned
4. if it still fails, go up the tree, clear more bridges. and try again

Yinghai pointed out that the new pci_scan_slot() crashes when called
on an ARI-capable slot that is empty. Fix this by exiting early from
pci_scan_slot if there is no device in the slot.
Also make next_ari_func() robust against devices not existing in case
the ARI capability is corrupt. ARI also requires that the devices be
listed in order, so if we find a function listed that is out of order,
stop scanning to prevent loops.

Currently, drivers/pci/quirks.c is built unconditionally, but if
CONFIG_PCI_QUIRKS is unset, the only things actually built in this
file are definitions of global variables and empty functions (due to
the #ifdef CONFIG_PCI_QUIRKS embracing all of the code inside the
file). This is not particularly nice and if someone overlooks
the #ifdef CONFIG_PCI_QUIRKS, build errors are introduced.
To clean that up, move the definitions of the global variables in
quirks.c that are always built to pci.c, move the definitions of
the empty functions (compiled when CONFIG_PCI_QUIRKS is unset) to
headers (additionally make these functions static inline) and modify
drivers/pci/Makefile so that quirks.c is only built if
CONFIG_PCI_QUIRKS is set.

The Alternate Routing-ID Interpretation capability allows a single device
to have up to 256 functions. They can be populated sparsely, so the
current technique of scanning every eighth function is not guaranteed
to find them all. By introducing a 'next_fn' function pointer, we can
use the linked list of functions in the ARI capability to scan all the
functions which exist.
We can then speed up the pci_scan_slot by skipping the scan of subsequent
devfns for PCIe devices which are the direct children of Root Ports or
Downstream Ports. These devices are only permitted to implement device
0, unless they are ARI devices, in which case they'll be scanned by the
ARI code above.

This is a Soekris board, and its BIOS sets the size of the PCI ISA bridge
device's BAR0 to 8k. In reality, it should be 8 bytes (BAR0 is used for
SMBus stuff). This quirk checks for an incorrect size, and resets it
accordingly.

The aer_inject module hangs in aer_inject() when checking the device's
error masks. The hang is due to a recursive use of the aer_inject lock.
The aer_inject() routine grabs the lock while processing the error and then
calls pci_read_config_dword to read the masks. The pci_read_config_dword
routine is earlier overridden by pci_read_aer, which among other things,
grabs the aer_inject lock.
Fixed by moving the pci_read_config_dword calls to read the masks to before
the lock is taken.

It turns out that some PCI devices require extra delays when changing
power state from D3 to D0 (and the other way around). Although this
is against the PCI specification, we can handle it quite easily by
allowing drivers to define arbitrary D3 delays for devices known to
require extra time for switching power states.
Introduce additional field d3_delay in struct pci_dev and use it to
store the value of the device's D0->D3 delay, in miliseconds. Make
the PCI PM core code use the per-device d3_delay unless
pci_pm_d3_delay is greater (in which case the latter is used).
[This also allows the driver to specify d3_delay shorter than the
10 ms required by the PCI standard if the device is known to be able
to handle that.]
Make the sky2 driver set d3_delay to 150 for devices handled by it.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14730 which is a
listed regression from 2.6.30.
