bnxt_en: New Broadcom ethernet driver.

Broadcom ethernet driver for the new family of NetXtreme-C/E ethernet devices.

v5:
- Removed empty blank lines at end of files (noted by David Miller).
- Moved busy poll helper functions to bnxt.h to at least make the .c file look less cluttered with #ifdef (noted by Stephen Hemminger).

v4:
- Broke up 2 long message strings with "\n" (suggested by John Linville)
- Constify an array of strings (suggested by Stephen Hemminger)
- Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
- Use PCI_VDEVICE() to populate pci_device_id table for more compact source.

v3:
- Fixed 2 more sparse warnings.
- Removed some unused structures in .h files.

v2:
- Fixed all kbuild test robot reported warnings.
- Fixed many of the checkpatch.pl errors and warnings.
- Fixed the Kconfig description (noted by Dmitry Kravkov).
