Separate the PCI device object handling code

Currently the PCI device object includes several functions like
alloc/free/claim etc. However, the NovaObject should not be used
this way, and it makes the PCI device object really different
with other NovaObject implementations.

This patch duplicates the PCI device handling code as separated
functions. No logic changes but simply code copy. A later patch
will delete the code at PciDevice object.
