This patch removes all of the unused defines from the .h files contained in
igb.  For some defines there was a use and so I plugged them into the correct
locations.

IP Checksum enable doesn't need packet split in order to function.  It only
requires the use of advanced descriptors which the current igb driver does.
So we can enable it always without any issues.

This patch:
- increases the precision of the receive/transmit interrupt
  coalescing register value computations by using 64bit temporaries;
- adds functions to read the current hardware coalescing register
  values and convert them back to usecs;
- exports the {get,set} {rx,tx} coal methods via the standard
  ethtool coalescing interface.
