> Add module register and probe functionality. Add the required support
> to register IXD PCI driver, as well as probe and remove call backs.
> Enable the PCI device and request the kernel to reserve the memory
> resources that will be used by the driver. Finally map the BAR0
> address space.
> 
> For now, use devm_alloc() to allocate adapter, as it requires the
> least amount of code. In a later commit, it will be replaced with a
> devlink alternative.
