First part is for_each_pci_resource support:
Now pci device resource iteration is done via "for (i=0...)" open code.
That make code hard to read esp when only bridge or sriov resources
are involved.
We want to replace those open code with for_each_pci_resource() to make
the code more readable.
Also will add addon_resource handling, and need to make addon resource
to be treated as normal PCI resources during iteration, add
for_each_pci_resource will make that support transition more simple.
To make for_each_pci_resource more efficient. We will use preset bitmap
of different type for searching next idx.
Second part is addon_res support:
Now there is some non normal pci resources other than standard,rom,
sriov, bridges.
Some could be same as standard reg, but using different position.
Some could have own way to read/write to them.
Kernel are using different way to hack those resources like abusing
pci bridge resource spot on non bridge pci device.
Add addon_resources list in pci_dev for those non-standard resources.
With this patch, will treat addon-resource like standard resources with
special ops.
At last replace some quirk_io with addon_res.
could get from
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-pci-for-each-res-addon
-v4: split one patch out, and remove PCI_NO_....
Notes: We still need to keep _idx as we use it all the time, and drivers still
use them to get resource.
