[Intel-wired-lan] [PATCH iwl-next v1 1/2] igb: simplify pci ops declaration

[Jesse Brandeburg <jesse.brandeburg@intel.com>]

The igb driver was pre-declaring tons of functions just so that it could
have an early declaration of the pci_driver struct.

Delete a bunch of the declarations and move the struct to the bottom of the
file, after all the functions are declared.
