SR-IOV Patch Series 1/7: PCI Infrastructure Refactoring

[Ryan Stone]

This set of patches refactors the PCI infrastructure a bit to offer
some new APIs that the SR-IOV infrastructure will consume.  The
intention is that these refactorings should be no-ops for the existing
APIs.

[PATCH 01/21] Refactor PCI device creation

Refactor creation of PCI devices into helper methods that can be
used by the VF creation code.

[PATCH 02/21] Refactor PCI resource allocation

Refactor PCI resource allocation code to allow a request for a
memory-mapped I/O window that is a multiple of a requested size.
This is needed by the SR-IOV code because the VF BARs are all
allocated contiguously.  We can't just allocate a resource that is
a multiple of a single VF BAR because the size of an allocation
implies its alignment requirement.
