Pass all SR-IOV configuration to the kernel using an nvlist. The
main benefit that this offers is flexibility. It allows a driver
to accept any number of parameters of any type supported by the
SR-IOV configuration infrastructure with having to make any
changes outside of the driver.
It also offers the user very fine-grained control over the
configuration of the VFs -- if they want, they can have different
configuration applied to every VF.

Add a function that validates that the user-provided SR-IOV
configuration is valid. This includes basic checks that the
structure of the configuration is correct (e.g. all required
configuration nodes are present) as well as validating against
a configuration schema.
The schema validation consists of:
- Ensuring that all required config parameters are present.
- If the schema defines a default value for a parameter,
adding the default value if the parameter is not set.
- Ensuring that no parameters are specified in the config
that are not defined in the schema.
- Ensuring that have the correct type defined in the schema.
- Ensuring that no configuration nodes are present for devices
that do not exist. For example, if 2 VFs are configured,
then we validate that a node called VF-5 does not exist.

Implement the interace to create SR-IOV Virtual Functions (VFs).
When a driver registers that they support SR-IOV by calling
pci_setup_iov(), the SR-IOV code creates a new node in /dev/iov
for that device. An ioctl can be invoked on that device to
create VFs and have the driver initialize them.
At this point, allocating memory I/O windows (BARs) is not
supported.
